The Renogy 3000w inveter should run one AC with a soft start. Sounds like you should do more troubleshooting first. Another inverter isn’t going to solve the problem unless that inverter is just bad.

Welcome aboard, Links are in the description area 👍. A lot more to come.

I would keep the equipment unless you have a buyer thats willing to pay enough to recoop your losses on the setup. If you plan to do the same setup in a new RV just keep it and move it over. I’m installing a second inverter, that video should be out soon.

Was that a question? I’m not sure if what you’re asking.

A lot of good options out there now compared to a few years ago 👍. Does Sunglow have power assist like if you’re on 15a or 30a hook up?

@@saltytrips What it does is if you have, say, 15 amps coming in from the grid, it uses this to charge your batteries in tandem with your solar, powering your RV with the 5,000w PSW inverter. The limit for grid battery charging for my model is 40 amps (which can be adjusted down so you don't trip a breaker if you are on a 15 or 30 amp service) up to a maximum combined charging amperage of 100 amps. It also allows for a max of 63 amps (7,560 watts) bypass from the grid to power your RV without using the inverter. I have sufficient solar, so I don't need to connect to the grid or run my generator anymore. I don't use this option, but if you don't have enough solar you might enjoy this feature. It will also work without batteries allowing you to use either solar or grid power directly, say if you temporarily disconnect your batteries for maintenance or repair. One of the reasons I purchased this unit is that it will accept 500 volts of solar input. My array puts out around 330-350 volts under load and 400 voc. This keeps the amperage down and lets me use smaller wires with no power loss. The inverter is 95% efficient, the same as the Victron and it has a power saving feature that drops the normal 40-50w idle power consumption down to 20-25 watts when not in use. I have this feature disabled, but those with limited battery capacity might find this useful. Here's a link to the company's website if you have more questions about this model. sungoldpower.com/collections/power-inverter/products/5000w-48v-solar-charger-inverter They have many more models too. This one suited my needs perfectly, but others may be right for you. One of the reasons I chose this company is I met a fellow FT RVer in Quartzsite who has been using a Sungold Power inverter reliably for about 10 years and he recommended them. There are cheaper ones out there, but they are, well, cheaper. They have a nice 6,500 watt/120a model with built-in Wi-Fi (it's a $100 option for mine) that's only $1,100, but its max voltage is only 390 volts, which is sufficient for most people but just short of my needs. Take care, Chip.

will your system run both ac’s when hooked up to shore power?

@@kurtmcclelland1086 Yes. Both ACs together draw a max of about 2,500 watts due to the micro aire soft starter on my rooftop AC, though they typically draw under 1,700 watts running together. A 30-amp connection will provide 3,600 watts. If hooked up to a 15-amp extension cord, this power will be used to charge the battery and the battery (or solar) will provide the power needed to run all loads, up to 5,000 watts (surging to 10,000va briefly if needed). If I need more wattage than this, I have another 1,000-watt inverter connected to my 560ah 12v bank that is wired to run my entertainment system, desktop computer and a few other select items, that will reduce the load on my 48v system, effectively giving me 6,000 watts of inverted 120v power. But frankly, I tested it with both ACs and the microwave on and it never drew more than 80% of the inverter's capacity, according to the power usage meter on the inverter, without my 1,000-watt inverter being used.

thanks

When on shore power the inverters aren’t needed to power anything , shore power runs the whole RV.

If you plan on running 14kw of battery you may want to really consider stepping up to 24v or even 48v. Our system has 15kw of battery and we are running 24v. Do what makes you happy just be safe 👍

@@saltytrips I've thought about it. If victron offered a 2X120 multi plus in 48 volt I might have gone with that. I don't feel like 24 volt offers me that much given the pretty short high amp cable runs for my install location and since I don't intent to go past 3000VA inverter capacity or 300 amps dc which imo is about the maximum it makes sense to do with 12v. The 14kwh is a potential future upgrade that may never happen if I get a small generator setup to feed off the big chassis fuel tank like I want..

Right on 👍

Depends on your application, rule of thumb is 1.25 x max working load amps. This is a 24v system so technically I can use 1/0 cable but went 2/0 for extra precaution. I have a 300 amp fuse on shunt, 150 amp fuse for MP2 and 80 amp fuse for Orion 24 to 12 converters. Just depends on your application.

My application will be a 12 V system. Using li time 230 ah and a Victorian 100 50 Solar controller And for the solar array will be. Cigs stick on 2 ,drilling no holes into the rv traler roof, wat 2 of them total 400 wat. for now And will expand. I could not find any information anywhere. For the mega fuses. What size to purchase? For the links distributor. Thank you so much for Responding to my question.yes I will be using 2 ought cable. Most of the System throughout .

@@johnsenesi9095 if you’re running 12v system you really need 4/0 from battery to distributer and to inverter.

@saltytrips ok I'll order 4/0 instead of the 2/0 aught.. ok now what about the mega fuses? What do I order to what application? What size wire Do I run to the solar Victorian distribution100/50 size Over to the linkes distributor bar.

@@johnsenesi9095 fuses should rated at 1.25 times max amperage working load. Here’s a charter for determining wire size to account for amperage load and length. www.bluesea.com/support/articles/Circuit_Protection/1437/Part_1%3A_Choosing_the_Correct_Wire_Size_for_a_DC_Circuit

You're wrong on extension cord being weakest link too. Most of the bigger inverters (like mine) have ability to run 10ga Romex directly to inverter, to transfer switch, to panel

@@joshuahayes2564 nope, 12awg is rated for 25 amp (120v would be 3000w) at 20 ft and at 30 ft only rated for 20 amps. Most 5th wheel RV are more than 30’ if your running 12awg 30’ at 25amps its over its rating and could cause fire. Gauge wire all have an amp rating and it reduces over distance which is a safety factor for people to consider so I’m absolutely correct on both accounts, transfer switches are not UPS, there will always be an interruption. So whether its a millisecond or 30 seconds it doesn’t matter, has the same effect

I explained the major differences between cheap “vs” the Multiplus in great detail, and covered several other options. Thanks for watching.
