Yes. We did find some loose connections. Tightened those and let tgecsun do its thing. Turned off the trailer fridge and still had to run the generator for a while after sunset. Dropped the cutoff to 20v. Power out again this morning. Of course it's cloudy today so will probably have to run the...

I have an MPP Solar lv2424 hybrid inverter. 4x rich 100ah 12v Lithium batteries wired in a 23v configuration for 200ah. Sunny days here. My AC power consumption is for charging tool batteties and computer. I have a separate DC distribution box connected to the batteries for lights and phone...

I have 6 200w 12v panels and 6 100W Panels with the following specs: Power watts Pm 200 100 Max Pwr voltage Vmp 20.4 18.5 Max current amps Imp 9.8 5.4 Open Circuit Vltg Voc 24.3 23.2 Short Crct amps Isc 10.2 5.7 Max Voltage DC 1000 600 Max Series Fuse Amp 15 10 PMAX Coefficient...

Here are the spec stickers from my panels.....

You're right, its 5.4amps. Was looking at the 200w sticker. Thanks for the info.

I have 6x 200w, 20.4Vmp, 9.8a Imp and 6x 100w, 18.5Vmp, 9.8aImp. The online calculator for 3s4p shows that there will be 1687W, 55.5V and 30.4 amps going to the MPPSolar LV2424 once I combine it all. I am trying to size the combiner to support it. It would be easier to buy pre made but I am not...

I hope you are wrong about 24v or it is still has some years left in it. I have too much invested in 24v. The cost of keeping up with technology I guess. Thanks for the input.

Hi, I am in experiment mode on a small 12x16 shed that I have set up very minimal electrical usage in preparation for a total off-grid 600sf cabin. It has 12v USB charging ports, lights and a small 12v Cosco fridge. There are a couple rarely used 120 AC outlets. I have 2 12v Lead Acid batteries...

Thanks. I have a 500 gallon water tank and it does get filled up in about an hour with my Costco Firman. I definitely don't want to be starting and stopping the pump each time I turn the spigot on. The only real reason I want to go to a solar pump is to get off reliance on gasoline. Once the wet...

Thanks, I was at Costco yesterday and was looking at their generators. You are probably right in that getting the pump on solar would be a lot of money for the little amount I use it.

That is a good point. My pump is pretty deep so keeping it healthy will save money in the long run.

Good info. I thik I have access to an amp meter that will check the start up draw.

Thanks, That is great information to have before I get moving on any design changes. the Pump is at about 350 ft so it tkates alot to get going. Right now, I have a gas powered generator that does the job but would like to add to my options someday as a fall back if I cant get into town to fill...

I don't have the MPP Solar LV2424 specs in front of mine. Assuming they haven't changed since I bought it a couple years ago, the website says max 2.7kw output at 24vdc. I can't tell from a quick search how much wattage the inverter uses. I am using End Of life Deep cycle Lead Acid so its hard...

I am getting close to pulling the trigger on some 12v batteries for a new 600 sq ft totally off grid cabin I am building. I was working towards a 24v setup by purchasing the MPP Solar 24v charger/inverter with a 24v to 12v stepdown for my shed with lights and a Mini Cosco refridgerator. Works...
