    How to replace 2 SoK 12V BMSs with 1 24V BMS?

    well there English isn't the best. Here's what they said. "Growatt inverter, when turn on or off, it has a very high peak current, it would burnt the BMS" so then I asked about compatibility with Growatt and they said "No, SOK Battery support, but GROWATT inverter issue, it easily burnt BMS...

    How to replace 2 SoK 12V BMSs with 1 24V BMS?

    I have 2 12V SoK batteries wired in Series to a 24V Growatt. I have been dealing with BMS issues while traveling in Alaska. After talking with SoK they said the Growatt system as a high spike in voltage when turning on and that it burns out the 12V BMS included in the batteries. They told me...

    In Alaska have issues with lithium batteries not charging correctly

    I just got this info and sent it to them, per their request yesterday. It would be great if they got my email and responded this weekend since I've been trying to get a response from them since the 30th but it's the weekend again and I don't think they work on the weekend. At least I'll be...

    In Alaska have issues with lithium batteries not charging correctly

    I did charge them both to approximately the same voltage the day after the 17.1 volts. 13.37 and 13.35. Then put them back together and all the same issues of the one being wonky. I was originally told to charge each battery to full on set up and then put them together. I also charged them...

    In Alaska have issues with lithium batteries not charging correctly

    Also Can you explain why you can't pull the system apart and use 1 battery, if that's what you are saying, and then put it back into the system? I mean I can take 1 AA (out of 3) out of my headlamp put it into something else and then put it back no issue. Its not exactly the same for an...

    In Alaska have issues with lithium batteries not charging correctly

    I'm saying I unhooked the batteries from the system and each other and had 2 separate 12v batteries. I then used one of the 12V batteries and bypassed the all in one and just hooked it up to the 12v camper system like you would normally do.

    A/C pulling from Batteries instead of Generator with GROWATT at High Temps and High Altitude

    Thank you very much for your technical answer. The inverter seems to trip in the first few minutes. We did get cool air one time for about 10 minutes before it tripped the others were within a minute so it sounds like your issue. I had originally planned on installing a soft start but then...

    A/C pulling from Batteries instead of Generator with GROWATT at High Temps and High Altitude

    Hello all, I have a GROWATT 24v 3000 all in one and 2 SoK 206ah lithium batteries. I installed this system back in October and everything has been working great, except for the A/C. My test run failed after a few minutes as I tripped the BMS in one of the SoK's. I realized I had the settings...

    Batteries loosing power quickly....worked fine for 3 months

    The OEM converter is disabled, first thing I did. The jack wiring has nothing to do with mine and my wiring is completely separate other than where it ties into panel. Which of course now links it up. There is a power on/off switch for the old battery set up which goes to the jack. My wife...

    LNEX Battery Monitor not reading correctly on 24v system

    Hello all, I got my System finished today and everything is working great except the battery monitor. I originally programmed it for the 12v settings, lol, but I have a 24v system. I changed the settings to double what I had for the 12v but it's still reading 100% which it can't be. Do you...

    GROWATT 3k - Better place to mount Under Bed or in Pass Through???

    Hello all, I got my Growatt 3k 24v inverter last week but never turned it on. One of my SoK's had a bad BMS and they are shipping me another tomorrow. I'm debating putting it under the bed or the passthrough. Under the bed means easier access and I regain a lot of room and a door to access...

    Solar Panel mounting on curved roof - the inside information

    I have the same issue. Trying to put some 39" (ish) panels in a 39" spot. I used the Z brackets on my last set up and with the very curved roof on my new ORV I will need to use something like that again. I really just need a mount that I can attach to the Z bracket and panel to extend it out...

    Need a Lithium Battery Charger for initial charge.... recommendations?

    Thanks! SoK said they are shipped at 30% soc so 8 hours each it looks like. I'll also be running in series but watts 247 has a battery balancer that you can install for cheap that keeps them always balanced he says.

    Need a Lithium Battery Charger for initial charge.... recommendations?

    Hello group. I'm picking up my 2 SoK 206ah Lithiums on Monday and then need to charge them. I'm picking up the rest of the system for install Tuesday/Wednesday. I full time and will have solar or a genny to always charge the batteries so I don't for-see ever needing to use the charger again...

    MPP LV2424 A/C Input and shore / Generator Power ???

    So I was doing some thinking and if I have the generator power come in and then the A/C split off from the panel, the generator will power the A/C and the MPP will power the air fryer is what we were thinking BUT. The MPP pulls from generator power first Sooooo it will try and power the air...

    MPP LV2424 A/C Input and shore / Generator Power ???

    Sorry went to bed early, EXACTLY what you said are the scenarios I for-see happening. 3) is the catch. I want to be able to run the AC and the Air fryer at the same time. Yes some units like the victron have a "Boost" from the batteries. I have seen that in the advertising for the unit but...

    MPP LV2424 A/C Input and shore / Generator Power ???

    The generator is 2500 watt (1850 continuous) Using the air fryer to cook would take 1450 continuous & the A/C is 1450 watts (in desert conditions, 105 degrees, 1700 watts). So 3150 watts total MAX scenario. I thought the unit was capped at 2400 watts but I don't know how to read that, sounds...

    MPP LV2424 A/C Input and shore / Generator Power ???

    Far right column is the 2.4KW unit, so 40amp. But I'm curious how do I run my generator plugged into the shore power to power the Aircon but have the MPP powering the rest of the rig? Someone said the MPP pulls from grid power first so it would try and use the generator to power the A/C AND...
