I ended up building out a 120 system with a single 24/3000 multiplus partially due to space constraints. Project was put on pause for a few months. I've got the second unit if I need it and can fit it in. Rehashing my usage, I'll be very infrequently above a 2kw threshold.

Cool, thanks

Shorted battery in question is an 8s 24v EVE 280ah None of the cells blew their safeties. Most of the cells appear in good visible shape with no bulging. Minor bulging occured on the two terminal cells. These were all top balanced to 3.65v and matched voltage before the incedent. Now they...

I recently purchased 2x 24/3000 multiplus' with the intent of running them in parallel for use with 120 volt US appliances exclusively. I planned a system with some breathing room for a complete electric appliance loadout on my bus conversion. I purchased what I thought to be a high efficiency...

I'd consider it if you're willing to pickup the cost of shipment. I'll have to see how Involved a repack is.

Total cost to you guys is $280 per panel upon pickup. Better than $.50/watt for a new large high efficiency panel, perfect for bus builds. If anyone is interested please let me know. I may ask for a 50$ deposit depending on how this goes. If I get enough interest the order will take a month or...

I've been looking at different panels for my bus conversion. These have pretty optimized specs for my setup: https://www.alibaba.com/product-detail/600-Watt-Solar-Panel-600-Watt_1600195383299.html?spm=a2700.galleryofferlist.topad_classic.d_title.56f55351ouHvt2 280$ per unit 600 watts...

How do I calculate the size? I've got 1/0 wire on the way which should support well over 100 amps for the distance. The bus bars are oversized to support up to 150 amps but the BMS is only rated for 100 amps. Is 1/0 large enough?

I'm building 2 24v 8s battery packs with 280ah EVE cells. Each 8s pack will have it's own 8s overkill BMS. I've picked up Milwaukee packout crates for battery boxes. It seems like good practice to keep the cells as close together in a pack with equidistant bus bars of the same material...

See, this is what I originally thought, however: 1. These are high temp silicone insulated wires 2. are fairly short (roughly 12'' each side) These 2 parallel 10 AWG wires are equivalent to one 7 AWG wire which at short length has a much lower voltage drop. The reseller says it can handle the load

Looking through the overkill BMS thread https://diysolarforum.com/threads/overkill-bms.16318/ looks like the 2 default 10 gauge wires are properly specc'd for 100 amps.

I've got 2 100a 24v 8s Overkill Solar BMS'. Looking at wire current ratings, it doesn't look like the 10 gauge stock wires are going to cut it. It seems that 6 AWG wire would leave a good safety margin at 100 amps continuous, problem is, I'm not sure they will fit the 4 solder points. is 8 AWG...

Let me know how that portable pack goes. I played around with the idea of using a milwaukee packout as a battery box and storage for the inverters. Easier to wheel around and work on.

Hey there, I'm between Sacramento and Tahoe. Town called Pollock Pines. around 2 hours on a good day from Oakland. If you haven't already run an audit, snoobler has a great spreadsheet in his sig. It'll help manage the needs and expectations of your system. Sizing the inverter is all about...

Alright, pulled the trigger on 2 multiplus 24/3000 120vac units. If you've got the space this seems like a better choice than 1 quattro because it gives you a higher peak wattage with redundancy. So far, I'm happy with the decision. For anyone looking I was able to find them on ebay through...
