At 2:31 you address the noticeable different charging from different controllers. Many of us are calls this fighting and unproductive charging. Some controllers even have communication ports to stop this fighting. If you had a video addressing this subject it would be beneficial. I see quite a few of these are being made, and they don’t agree with each other.

Hi there. First of all, thanks for your videos. They're really helpful. I have battery bank (2x220 48v lifepo4) and an anern ex-pro 10.2kw inverter/charger/mppt with a 8kw PV array. I'm planing to add one more anern 10.2kw inverter/charger/mppt with its own PV array. These anern aren't paralellable. The AC out of each goes to an automatic transfer switch. So, if one inverter fails, the other takes the load. Do you know these inverters/mppt? Do you think they can be connected yo the same battery bank? Of course battery parameters should be exactly the same.

I have have a kind of unique situation I'm wondering about. I'm installing a solar panel array to temporarily power my RV at our RV pad, but would also like to use the same array to power a seperate inverter/battery bank to power a 240v system for our well. The idea is that when one system is full, it can be used to power the other, and vice versa, and share the load when both needs it. Is that possible for both to be connected in parralel to the same PV array as inputs to charge 2 completely seperate mppt controllers/inverter/battery banks?

I think i need a power diode on the output of one of my 2 (cheap,blue ones,china) controllers,they are both in parallel to 24 V batteries,they interfere with each other , the 2 amp meters oscillate a lot when the load is small and the sun is out; also, they never let the voltages go to 14.2 either (i have six panels of 60 cells, maybe that is the problem,should be 72 cell?; they are in 2 strings of three). i guess i will have to spend the money and wire the panels in series for 60 volts and buy an MPPT?

@phocos-global 8 ай бұрын

Thank you for reaching out and sorry for the delay. According to our technical team, since you have chosen 24V panels, we assume you are using PWM charge controllers. We recommend to use a panel with a Voc about x1.5-2 the battery bank voltage when using PWM controllers, so, for a 24V battery bank system we recommend a panel Voc of about 35-50V. To properly size your solar system you should make sure that your charge controller can handle the full short circuit current of your panels when using PWM controllers. So, you should make sure that the short circuit current of your x4 415W panels in parallel does not exceed the current rating of the PWM charge controller you choose. If the short circuit current is 10A, and you have 4 in parallel, you will need a 40A charge controller (like the CXNup40) Also, make sure that same current does not exceed the charge current rating of your battery pack.

Hello, it’s worth considering that the PV side on the family of PSW-H inverters require a “minimum” DC voltage to operate. This can range between 90-120Vdc depending on the PSW inverter you are working with. However, it’s fair to mention that our line of Any-Grid inverters was entirely designed with solar in mind. Out of the box they do not come equipped with the safety features that a wind turbine charge controller or inverter would come pre-equipped with. Both power sources are not the same (one being mechanical the other being EM radiation). With that said, we cannot speak for a use case outside of what this product was designed to do.

Question I have 2 PowMr 24v hybrid inverters 3000w each I have 24v 600ah Lipo4 battery bank can I connect both inverters to the 1 battery bank? But can I connect 4000w solar panels to 1 Inverter to charge the batteries ? The reason why because I don't want to split the panels in half and run another set of wires from my roof down to the garage it's to much work

@phocos-global 8 ай бұрын

Thank you for your comment, unfortunately, we cannot provide any technical support for products not made by Phocos - But, if you were using 2 Phocos PSW-H-3kW-120/24V inverters, you could connect both to the same battery bank and then only connect solar to one of the two inverters. With Phocos equipment, it is not necessary to have the same PV power on each MPPT. Please visit our website www.phocos.com to see a list of Phocos distributors near you.

I'm running 18 group 24 gel mk's but there different ages so each one has it own charge controler connected to a main trunk line from my 27 pannel array that acts like wall on my porch (mounted vertical). All of positive lines are bolted down for safety reasons. I only play with the negative lines, one from panel bus bar and one from the batterie bus bar. I haven't see anyone doing this. I might make video one day, because not everyone got the money for a huge bank.

I use 3 controllers...as I have 5,020 watts I'm panels going into the battery's.. I use 2 x plasmtronic pl40 ( 40amp each ) for the solar plus a plasmtronic pl20 controller for wind 600watt.. my system is hybrid. Wind and solar. I use the wind controller that came with the wind turbine linked into pl20. You can put the controller onto battery or you can use a bus bar to link the 2 together ( power out to battery ) it really depends on what you want to spend. Hope that helped

@phocos-global 2 жыл бұрын

Hello, two controllers can be connected directly to the battery as long as the same wire length/thickness is used for each controller and the voltage drop is kept minimal. A bus bar is thus not required. It does help when more than two systems are paralleled for high current distribution and to make connections to the battery bank easier.

Asalamualeykm I would like to know the reason for using 200 AH Lead Acid battery as the minimum capacity with 3/5 KW phocos inverter. Is it because :- 1. From Charging point of view that the battery charging current from the inverter to the battery cannot be programmed less than 20 A (max charging current for 200 AH battery on normal operation) and charging via solar in case of no grid can damage lesser capacity battery?? And/Or 2. From Load point of view such the inverter when operating in pure battery backup mode (no solar and no grid available) the minimum capacity has to be 200 AH to cater to 3000 Watt of rated load ?? 3. If my inverter is configured in a way that the connected load on AC output side of inverter is less than 1000 watts (the max emergency load in case of power cut or grid failure) and the inverter is mostly operating in grid feed in mode, then a. Can I use 100 AH/150 Ah batteries with the inverter for minimum backup requirement...?? These are the queries I am getting from clients who want to upgrade their existing On Grid systems to Hybrid Systems and I suggest Phocos inverter for the same. The concern of the clients is that adding 200 AH battery adds to overall cost of upgradation since power cuts are minimal, back up requirements are basic and Solar power is utilised majorly in grid feed in mode. Waiting for early reply. Thank you

@phocos-global 2 жыл бұрын

Hello, the charging current can be reduced down to 10 A on any PSW-H inverter, that is not the reason we recommend at least 200 Ah. It is indeed to ensure stability at all possible AC load levels up to the rated inverter power. To create AC on any inverter, the current drawn from the battery is not uniform. While high-frequency inverters such as the PSW-H are better in this respect than larger transformer-based ones, converting DC to AC always causes some level of uneven current draw on the DC side. Our recommendation ensures that the battery bank can cope with that and provide the necessary current to supply AC loads at the inverter’s full power potential. If you use significantly less power than the rated power of the inverter’s AC output then yes, you can decrease the battery capacity to some extent. We would never go below 100 Ah though, unless using lithium batteries capable of currents at over 1C. Alternatively, when using very small battery banks and lithium is not an option, vehicle starter batteries can be used (as opposed to the usually recommended solar / deep cycle batteries), as they can handle higher currents at the detriment of life expectancy and deep-discharge capabilities.

@5400bowen Жыл бұрын

And besides Phocos answer, you are not going to get many hours of use out of a smaller battery capacity if you are running an inverter of that size at anything above half of it's maximum power output. And even at half, you will run out of power early in the evening.

Hello, thanks for reaching out to us. If we are understanding correctly, you want to connect an MPPT inverter-charger to a 24V battery and a 12 V battery, where the 12V battery is connected to two PWM controllers? This is not advisable. You want your nominal battery voltage to be the same on all charging devices.

Hi, i upgrade my system from 24 to 48 volts i have now total of 12 solar panels,6 are of a higher wattage so my question is : Can I connect two MPPTs with two different wattage solar panel banks to the same battery bank? one MPPT with the 6 lower wattage solar panels and the other MPPT with the higher wattage solar panels.

@phocos-global 2 жыл бұрын

Hello, assuming the system is sized within the battery bank’s specifications, the short answer is, yes, this is ok for the PV side. MPPTs have a DC-DC converter that allows for this. The shared battery bank however must be a common nominal voltage that is compatible with the controller. For Phocos controllers this would be 12/24Vdc battery banks.

@phocos-global 10 ай бұрын

Thanks for reaching out, Troy. It sounds like your battery bank is undersized for your loads. You will need to consider the capacity of your battery bank to be able to provide adequate power to your loads at any point in time and for how long. Adding more solar charge controllers will not fix that issue, but may alleviate the problem during daytime when sun is available. 11.37 is very low voltage for an AGM pack, meaning the pack is being overrdrawn or overdischarged. Unfortunately we cannot provide insight or technical support for Victron products, but if you purchase any Phocos products in the future we will gladly support you via tech.na@phocos.com or tech.emea@phocos.com depending on where you are located.

Hello, thank you for reaching out to us. One fuse can be used, but it must account for the total current from all controllers. If you have any other questions, please reach out to our technical team here: www.phocos.com/contact/

@5400bowen Жыл бұрын

What that means is you have the outputs of the controllers connect together before everything goes through the fuse. Since it all will connect at the batteries, it can be connected before the fuse. But using separate fuses is a small increase in safety. And for a small increase in cost, you can buy inline circuit breakers that are also a disconnect switch. They are non resetting breakers.

If I use multiple charge controllers, would that mean they'll draw less wattage?

@phocos-global 2 жыл бұрын

Hello, each controller will still draw the same amount of power from the battery in order to operate (power consumption). The amount of power delivered to the battery (from solar charging) by each controller will depend on various factors (battery state of charge, irradiance,..).

@5400bowen Жыл бұрын

A shorter answer is that each one will "draw" less wattage, but the total drawn from all the panels will be more, as you will be getting more efficiency with each charger working farther from the high limit of it's operational power range. It's the same as two people lifting a weight as opposed to one. I'm assuming that the power output of the panels is less than the limits of the charge controllers, and the battery bank is large enough to effectively absorb (not be overloaded by) all the energy it receives.

According to our tech team, we cannot recommend using charge controllers of different charge profile settings. As stated in the video, charge controllers can be used in parallel on the same battery bank only if their charge voltage setpoints are identical from factory or programmable by the use. If you cannot confirm that the voltage setpoints and temperature compensation functions are identical, do not parallel these two controllers. It is recommended to use multiple Phocos controllers set to the same charge profile.
