    RAW Cell Busbar Ampacity

    Completed a build of two 48v packs made up with 105ah EVE cells. The battery busbars that came with the batteries are 12mm wide by 2mm thick copper. According to the calculator in the link below, the copper bus bars that came with the batteries can only carry just over 28amps. Means this 48v...

    EVE 105 48v 2p16s build

    Started this build today. These small M4 x 10mm terminal screws kinda suck. I’m only trying to torque to 3nm (27 lb-in) but seems way too high, feel like I’m going to strip them out. Any advice on the torque? Paused until I figure this out. Where the BMS negative is connected I bought M4 x...

    6000xp Knockouts

    Ugh. I re-boxed my 6000xp for moving it to my cabin before measuring knockouts. Is the trade show pic before the 6000xp was released from @HighTechLab still accurate below? AC connections: Pic from Dexter months ago:

    EG4 6000xp - Battery Voltage Settings

    Received my 6000xp today, quickly hooked it up to a small battery bank to test it, limited charging and discharge amps for small battery and a few other tweaks. Connected load to a L14-30 plug (pulling abolute max 1800w) which then I use a generator cable to plug right into my Reliance Transfer...

    Cell Insulator Sheets

    Just ordered more 105 cells from 18650battery but they are out of insulator sheets. Any other options out there in the U.S. or something I could pick up at Lowes or Home Depot?

    Test a JBD 16s BMS with Bench Power Supply

    Hit the jackpot and found 2 BMS' I ordered years ago and never hooked up. Want to test them out without hooking up to a 48v battery. Is there a way I can test these with a bench power supply, I have a 30v-10a one but looks like I can get a deal on a 60v-5a one on amazon.

    Hello Old Friends

    I bought these batteries some time ago from battery hookup and were rock solid. Time to get them back in use with a fresh 2a balancer JK BMS. Nothing like remembering you have LFP cells for a 48v battery.

    EG4 6000XP Operating Temperature Range

    Seriously considering using a 6000XP in my cabin basement but the operating temperature has less tolerance than other inverters (32º-113ºF). Would it derate at 32º or below or will it cease to function. My lows for the past year have been within a few degrees (37ºF) of the lower end operating...

    Need BMS for eve 280 cells

    Pulling trigger on some 280s since prices are cheap and want to figure proof my new 48v build. Looking at SEPLOS v3 200amp BMS. Wish they had 300amp to pull full cell power, if needed but most likely will never go over 8k watts peak anyway. SEPLOS still seems to be the most inverter compatible...

    Victron Quattro vs Multiplus II

    Outside of the additional AC IN, are there any other differences in functionally to a MPII (not the x2 120 version)? Is there something in the MPII that make it easier to program, more ESS flexibility, etc?

    Another Dead 120/240v Inverter Generator

    Got to our cabin last night. Everything was dead, LBCO on inverter. Inverter Generator starts but won't power anything. Checked fuses, wires, etc and of course out of warranty. No one has 240v in stock but PLENTY of 120v. No it's not a Honda...this is my second time regretting not getting...

    Growatt With Solar Assistant and Home Assistant

    I know some people will crap on this post because it’s not efficiently using a solar inverter for its full intended purpose but whatever. Some are simply looking for a low cost backup solution for critical loads in their house in the event of a grid outage. That intent is what started me in...

    Senville Aura 24k MiniSplit Filter Question

    Not solar or electric related question so I apologize in advance but this is a creative bunch. The only filter on my Senville 24k is at the very top of unit which happens to be about 9ft off the ground. Anyone come up with a supplemental filter that can simply lay on top which can be easily...

    Critical Loads Panel Install (Extending Existing Circuits)

    My friend just got a few quotes for installing a critical loads panel (sub panel) directly next to main panel in prep for an inverter to run those circuits via an interlock on sub panel. All three quotes came back with significant swings of cost. I called the contractors with him and learned...

    Weird Runaway increase during load

    Anyone ever see something like this. Under load, one cell is increasing in voltage and another is sagging in voltage then the BMS cuts off charge/discharge. They are the cells right next to each other. This pack has a 5a active balancer always working above 3.45v.

    Testing Panels Facing SW @ 240°

    Does anyone know a site or calculator that I can use to figure out optimal fixed tilt at different azimuth directions? Trying to get some additional power from some SW facing panels. Tested today with 2 - 400w REC panels and got about 2kWh hours out of them. Forgot batteries were full so didn’t...

    Schneider BCS and XWPro

    Just watched the @SignatureSolarJames video on the BCS and have a few questions: 1: assume this is really only needed or good practice if you need more than one XW Pro. Assume you can use start with one XW and grow with BCS over time. 2: Trying to understand how the self consumption works...

    Grundfos 10 SQ07 Well Pump…Just Awesome

    Had to replace my well pump at my cabin and went with Grundfos SQ so it will easily start with inverter and/or generator without having a massive system. Buy once/Cry once. Old 1/2 HP Franklin was 34a (8100w) inrush and 7a run. Duromax 10k was only generator that could start this thing. New...

    Samlex America EVO-4248SP - Looks Impressive

    Has anyone used these inverter/chargers yet in the US? They seem pretty impressive for some moderate split phase power (4200watts with good surge). I have a call into Samlex America to see if they are stackable now or if they will be in the future. Benefits I see: UL Listed 1741 Low frequency...
