What happens if you don't have enough solar power while off grid? We use a generator to get us through the cloudy and stormy stretches in the winter. Usually this means passing the generator power through the inverter to the loads. But, there is another way. This is a review of the new 100 Amp charger from Signature Solar. They call it the Chargeverter.
The Chargeverter-5000 is a 5kW AC charger that can recharge most 48V batteries up to 100 Amps. It has a built-in circuit breaker on the battery side, DC. The AC cord comes pre-wired with a NEMA L14-30 plug. Most generators that have 120/240V will have this style outlet on them.
In the video I'm using a Honda EU6500 inverter generator running on gasoline. However, this charger can use almost any generator because it can be set to the maximum Amps. The AC input will also work with 120V. If you want to set this up as 120V, then you will probably want to change an adaptor to a 120V plug.

I think that is the best way to utilize a generator with solar. A few months ago I did the same but used a much smaller 48v charger. When I need to charge up my battery bank , I start the generator and run the charger only. You can really optimize your battery usage when you know you can quickly charge them up. If you calculate the cost of a larger battery bank to handle any eventuality and the cost of fuel for a generator, the decision to go this way is a no brainer.

I ordered and just installed my new charger. Out of the box one of the two modules had slipped out of the socket during shipping. Noticed this due to the unit providing only half of the selected charge current. A couple of issues worth noting; as David mentions the unit does not have a delay feature to allow your generator to warm up. I will be adding a timing relay to do this. Also this unit would not work with economy mode on my Honda EU6500. The charger would instantly fault when the generator was attempting to throttle up. When the charger faults it looses the voltage and charge current settings. With economy mode off the unit does a great job changing my lithium batteries and eliminates the sketchy transfers that my inverter/charger produced when the generator came online. I would like to see some added features but do think the unit is very useful at a good price.

Thanks for doing the test. I may eventually buy one if they appear to hold up over time. I have the Honda EU7000is and it can't start my 4-ton HVAC condensing unit even with a soft start. My Growatt 12k inverter likely can, so if I ever have a prolonged outage during a heat wave, I would be able to have the Honda run the Chargeverter while the Growatt runs the house loads and handles the large inrush spikes. This would prolong the run time of the 20kWh LIfepower4 battery rack provided that the average house load stays below the max continuous output of the generator which I converted to run on natural gas.

Nice charger. I wonder how long it will last? A 175 amp Anderson plug on the charger and your battery busbar would make it more useful for easy battery top-up when your solar can't keep up in winter.

@00000005547 Жыл бұрын

Alternatively you could also just rectify the 240v from the generator and feed it into a charge controller. Just have to make sure that it's within the charger max voltage. 240vac rectified is like 320vdc. This is actually how those big, tens to hundreds of kVA UPS systems work. Instead of using normal diodes they just use SCRs which are basically diodes you can switch off at the crossing point, this way they can control the output voltage and keep the batteries charged 24/7, while the inverter is always running producing clean AC I think it goes without saying that high voltage can be dangerous but is perfectly safe as long as proper safety methods are used.

Using a MidNite Solar CLASSIC 150 MPPT Charge Controller, Operating at 150 Volts with a Max Current of 96 Amps. And hooked to a #DC1248AC DUAL CORE PMG/PMA by Thermodyne Systems and powered by a 6+HP Diesel engine all for under $1,700 works the treat for me. It is cheap to build and operate and very efficient. We make our own fuel using waste Veggie-Oil that has settled for two weeks and filtered down to 25 microns. We add 10% gasoline and filter to 1 micron and use it in our diesel generator. All of our filters are polyester cleanable and reusable. So, we have an efficient generator and cheap fuel that cost between 3-9 cents per kilowatt hour depending on if it is a 10% summer or 30% winter blend. We live in Michigan where the grid is 17.4 cents per Kilowatt Hour. So, this cost is less than the power grid. Even if you do not make your own fuel, it is still a good way to make energy.

I wish this charger was out a year ago! Then I'd probably grabbed it. Right now, I just use a 16-amp 48v charger a few days out of the year to keep my 50KW battery bank alive. It seems to put out around 600 watts. It runs usually for 12-18 hours whenever I need it. I've got it connected to a 20amp Wi-Fi switch currently. So, I can switch it on and off remotely from anywhere. I guess next step would be to get it to kick in automatically when my batteries are low. But I'll probably just buy a generator or run 240v grid power to my solar shed. This way I could take advantage of my dual 100amp chargers built in my Victron inverter. The huge Victron inverters utilize software that helps them use less running power. I've seen my 15KW inverter running on 90 watts before.

If this is done correctly, that is on a off grid set up, you will be using the lower voltage instead of 240. If you built your set up to run only 110-120 v, you will be using a smaller generator. The idea is to use small generators not 240. The bigger the generator, the more gas you use. If you have a shorter charge time it maybe a better deal.

The hot exhaust air blowing on the DC cables might not be great, the insulation may begin to deteriorate over time. They probably should have routed those out the same side as the AC in instead, which would solve that problem and may allow for more efficient cooling.

Now, a request: Given that many of us off-gridders have been using "ordinary" (non-inverter) generators to charge our earlier generation (non-hybrid) systems -- mine is a Magnum 4kW 48v inverter with a Midnite Solar Classic 150 charge controller -- but now are embracing hybrid inverters, can you please kindly run this test again with any old non-inverter generator? Given that the guts of this Chargeverter come from the same Voltronics factory as the MPP Solar and EG4 hybrid inverters, it's crucial that we know the Chargeverter can accept "dirty" AC that our older inverters digested without issues. I don't want to have to buy an inverter generator to use this $400 charger! Best thanks!

My system was designed with help from the EG4 design department. Here's what they said in regards to something similar to your request: "If you wanted to use a generator to charge the batteries you would need a transfer switch to go from the grid to generator power since the inverters only have one AC input port. For a generator we recommend a generator with twice the wattage rating of your inverters. This is to account for dirty power. Dirty power tends to happen when a generator is operating at over 50% capacity and will produce voltage spikes and lulls that the inverters will not like. Since you have 13kW of inverter capacity it would take a pretty large generator. If you didn't want to buy a large generator you could use battery charger plugged into a generator." At the time, he pointed towards a different, smaller charger they had, but then the 5000 came along, so I think that it would apply as well, meaning, these battery chargers account for dirty power.

My battery bank is made of 6x EG4 batteries. Each EG4 battery is 100Ah. 6 in parallel means my whole battery bank is 600Ah. If I was at 0%SOC, and charged at the full 100A, then it would take 6 hours to charge the battery to 100%SOC. However, I don't suggest that approach. As I showed in the video, I'll be charging at 80A given my generator. And, I wouldn't wait until the batteries were dead, and I wouldn't charge all the way. It's far more typical to charge, perhaps, 40% of the total capacity in an off grid situation. That would be 600Ah*0.4/80= 3 hours.

At 14:17 I hope you flipped the DC cables on the top to the left side of the charger as having the hot exhaust air blow directly on those cables doesn't seem like a great idea. Not an expert, just seems logical to me, this is an awesome video. I am of the opinion that it makes way more sense to have a generator available to charge your system if you plan on going off grid so you don't need to go over kill with solar panels and battery capacity in order to make up for those cloudy days or poor weather. I think it's way more practical and cost effective, it also has the added bonus of having a generator available should your inverter ever fail. I feel like most people wouldn't mind needing to run the generator for a few hours to top up when weather is an issue, and since you are capturing most of the electricity generated it's actually not bad on fuel cost. What are your thoughts?

My goal is to cover my electrical needs with solar 99% of the time. That leaves 1%, or 3.65 days per year that I need to run the generator. I'm OK with that.

David, thanks for the video. I enjoy your videos, nicely done. I am not sure if I am seeing the benefit of using this unit to charge a battery bank. Are you saying the new Chargeverter is more efficient at charging a battery bank than the Schneiders and/or Growatts? Both inverter brands you have will charge the battery bank, I am not seeing the benefit, I guess. Do these inverters cannibalize power to charge battery banks vs when using a gennie? I bet I am over thinking this.

@DavidPozEnergy Жыл бұрын

Actually, the Schneider inverter is a little more efficient at charging the battery than this is. In my previous video I showed how switching the loads back and forth from generator to inverter can make the lights blink. This charger eliminates that.

I have a Larger generator. I know how to get the charger do that it won't over load my generator. my question is, can you parallel 2 or more of those chargers without damaging their circuit controller or the battery controller?

I just purchased one of the EG4 chargeverter, but it is showing 0.0amps on the panel and my amp meter. However, it is giving me 48v up 57v. Any suggestion what to do.

David, I have a question maybe you can help with. I just purchased an EG4 3000w 48V all on one inverter from SIgnature Solar and I was wondering if I can connect Redodo 12V 100Ah LiFePO4 Battery (4PACK) to the EG4 all in one inverter and will the BMS communicate with the inverter? I'd like to do this because I can't afford the EG4 battery and the rediculous $285 shipping charge.

David, loved all of your solar/battery videos. I learned a lot from your videos. I'm in Florida and setting up an emergency power backup system using EG4 48V batteries and 3000W inverter/solar charger/ac charger combo unit. Since I don't have solar, if the power outage drags on, my plan was to use the gas power generator to charge up the batteries. The Chargeverter seem like a perfect fit. The one question I have is how do you keep providing the AC power via the inverter while you are charging the batteries? It seems like if you connect the Chargeverter to the power rails on the EG4 battery rack and not disconnect the inverter, then the Chargeverter is just going to be supplying power to the inverter. If you turn off the inverter or disconnect the inverter, then you have no power to the house. What am I missing? Thanks.

@DavidPozEnergy 9 ай бұрын

I don't think you are missing anything. You said you plan to use a 3000W inverter, but didn't mention the generator size. The Chargeverter can go up to 100A, so if the battery is at 54V, that's 5,400W. If you haven't bought the generator yet, I'd look for one between 5kW and 6kW continuous rating, and limit the Chargeverter to 90A. Let's say you are pushing 5kW into the battery busbars, and you are pulling 3kW to your loads through the inverter. That means 2kW will be charging the battery at the same time. But, if your loads drop to 1kW, then you have 4kW charging the battery. You still have 5kW from the Chargeverter.

@@DavidPozEnergy David, that all makes sense. Thanks for the explanation. My parts are scheduled to start arriving this Friday. Wish me luck 🙂. Thanks again.

Thank you for the vid! It wasn't quite clear, wondering if you can you leave the unit off, fire up the generator, and then... come inside and throw the unit circuit breaker to start charging? Is there a reason to leave it on all the time or were you just showing what happens with battery only? .I ask because in my case it's a manual generator start about 200ft from the battery bank - e.g. start the generator without load and then go in and enable the charging at the battery but also cut-off charging at the battery if the generator struggles.

@DavidPozEnergy Жыл бұрын

I wasn't sure, so I just went and tested it for you. It worked fine. I had the AC side connected with the battery circuit breaker off. Nothing bad happened at all. Then I switched off the DC breaker first with the generator still running. Yes, that's fine.

hmmm video cut @8:54 ...? Can these be used "automatically"... i.e using AGS (Auto Generator Start) to start a generator with the chargeverter permanently connected to the battery and generator. No manual intervention any time. Will the generator bog down on starting etc. IF I had to, I could put my delay circuitry in between the chargeverter and the genny but.... It seems like this might not be intended for automatic operation.

@DavidPozEnergy 9 ай бұрын

I have it hooked up permanently to my battery, and to my generator. I don't have a problem, but my generator has a built-in delay for the Voltage output terminals.

Do you think it would have a problem with a non-inverter style generator? My APC & CyberPower UPS's always take exception to the generator power...

@DavidPozEnergy Жыл бұрын

I don't think there would be a problem. The power-supplies internally are most likely switch-mode units. Those don't care if you use perfectly clean sine-wave or not. I'd love to borrow an old style generator for demonstration. In the case of a small UPS, they are probably trying to qualify the electricity before switching over. Meaning, the power coming in has to meet certain specs and then the UPS moves the loads to the incoming power. This means the UPS is saying the generator power is not clean enough for the loads, and stays in back-up mode.

Thanks For your response. I Was wondering if you could power your loads from the charging power provided by the Chargeverter. I have a small gas generator, 2000 W, and this device may help me charging my batteries using my generator. I have a Schneider XW +so I have enjoy your recent videos on that inverter. Thank you again for your videos and please continue doing what you do.

@DavidPozEnergy I was wondering along with Charlies' question, IF you can safely turn on your INVERTER while charging with this new device? Will all that amperage fry the Inverter? I would think not, because they are ready to accept all the amperage from the batteries/banks, no issue... Your thoughts?
