    I like my two MPPT LV6548. I got them straight from the factory from peggy. The money you save is enough to ship it back if you ever have warranty issues and it took 3 days to arrive vs months on a boat through other sellers. She answered all my questions and helped setup the wifi app bc it...

    Bashen disappeared when I tried to get the warranty honored

    Updated the OP with pics You'll notice the flat edge of the level and the bulge which creates the gap seen on the sides. I then lined them all up shined a light behind them. You can see where they touch in the middle/ bulge and the gap shown from the light shining through. Here is the album...

    Santan solar was the best prices, best shipping price and packaging, will send 25 or less per pallet. I got 10 once. And on holidays their used solar farm panels are $35. I would only buy from them, not one panel was cracked on two pallets even after driving down my gravel road.

    Bashen disappeared when I tried to get the warranty honored

    FYI for future buyers doing research I bought 40 cells last year. I had 7 die that had bulging/warping and I'm watching a couple others for issues. I'm seeing fluctuations on the monitor of my batrium BMS that does not look good. Well, I guess they don't honor their warranty. They gave me the...

    Whats a good 48v battery charger

    There a very very few 48v lifepo chargers I guess for smaller generators you could get 48v 2000w MPP or growatt (MPP sister) and hook that up to the battery and just use the charger. I think the 48v ones all use the same charger with the same specs/paperwork when I was looking. I just didnt...

    Whats a good 48v battery charger

    Mine is out in the garage so none of that noise stuff matters to me. If I get a low charge day (100% off grid) then I start the generator to run all night and let the 2 gallons of gas burn through and shut off, thus the AIMS turns off. I can still get all 6000w of power without then generator...

    Any recommendation for buying Solar Panels in US.

    How many volts can you controller take in? Take the 3 panels and triple the voltage for 3s and see what you get vs need Is space an issue? Why are you trying to get such high wattage panels? If space is not an issue then lower wattage = lower heat and older proven panels/tech so more reliable...

    Ghost Controls gate opener; which battery to use for cold?

    I read the first part, too long. This worked good in 18 deg temps. lifepo/lithium will require a battery heating pad etc. Anyway, I got the kit w the solar panel. Bc of cold I went with a marine battery from costco d/t thier price and return policy. I got a dark blue (less brittle) plastic...

    Should I upgrade to a 48 volt system? advantages?

    48v = 16 cells in series = larger battery with less BMSs 48v = smaller wire and longer wire runs 48v = larger amount of panels input (watts and volts) MPP LV 6548 does 250v in 8000w max in

    Solar panels for 48v battery system

    Santan Solar has the best bang for buck. On holidays they have used solar farm panels for $35 (well that was Jan 2021 atleast) 25 panels was like $225 for shipping from AZ to OR its the same costs for less than 25 bc of the pallet space it takes up. I had them send it to a freight distribution...

    Generator only charge controller / charger for cloudy days or night time???

    I updated the OP with issues and solutions. You can have a Batrium k9 trigger a dry contact relay that starts the generator to charge at a certain voltage and stops at a certain voltage. Then the generator directly powers the Aims charger to avoid the pass through loads issue.

    Generator only charge controller / charger for cloudy days or night time???

    FYI, I updated the OP with the 3 legit brand chargers I could find. I also added my experience of the MPP once I got everything working. You need a big enougg generator and inverter style. The pass through current to the loads really sucks for smaller generators and keeps tripping my 3500w gen.

    Generator only charge controller / charger for cloudy days or night time???

    I ran into a couple issues after I got it running. I ended up getting the Harbor freight 3500 inverter generator bc there was only 2000w inverter generators around town. The issues are charging via the MPP first I'll give an example of best case scenario and how it should work using the MPP...

    Generator only charge controller / charger for cloudy days or night time???

    Worst case I have the aims charger coming. I went with the 3500/3000w harbor freight inverter bc the extra warranty is no questions return vs sportmans warehouse for a crapy firman generator. I have a new costco Yamaha 2200w coming also to run the aims charger all night for a gallon of gas...

    Help with MPP LV 6048

    My bad its the 6548 Turns out an obscure pdf only on their website details the generator specs. The gen has to be an inverter generator of similar wattage as the inverter. It has to be clean power or the 6548 will reject the source. If you want an auto start inverter genny then that is a...

    Generator only charge controller / charger for cloudy days or night time???

    Well the inverter shut off due to low battery while I was sleeping today. My wife picked up a new generator today after her work since I have to work tonight and couldn't.

    Generator only charge controller / charger for cloudy days or night time???

    No I just need to charge my 16s2p before it dies. I set to 10a and the 2200w gen wouldn't charge. It only showed 300w-ish going to the loads. If it wont charge 120v then I'll just get a charger. So I was asking what to get.

    Generator only charge controller / charger for cloudy days or night time???

    Hm maybe UPS vs appliance refers to the unit turns on like a UPS when power goes out and appliance means its a full time appliance.

    Generator only charge controller / charger for cloudy days or night time???

    Haha we did the same thing. Her first reply was 110v only works in appliance mode. I'm waiting to here back what appliance mode is. Total bs if you can't use a common gen to charge up. I think the chargers are EU chargers put in the units. Maybe go to mexico an buy one.... Arg this sucks bc it...

    Generator only charge controller / charger for cloudy days or night time???

    Also, its 240v ac input needed while they are paralleled. (Not 240v to the single 120v unit). I can tell.you.right now I have tried my yamaha 2200w inverter generator and a 3800w traditional generator and neither charged the battery. See the gen requirement manual on MPP's site

    Generator only charge controller / charger for cloudy days or night time???

    I asked peggy over at MPP if appliance mode still charges the battery. My interpretation was that appliance mode is it just feeds the appliances running directly
