It's a little OT for this forum, as I'm not really looking to use solar power for this, but I'm really looking for something that could serve as a UPS, running a constant load of about 100W, for a few hours--call it 300Wh or so--and using LiFePO4 batteries. Pb-acid don't seem to last long in...

Since it's pretty well all up and running now, here's what I have set up in my workshop. I'm using eight 250W panels from SanTan Solar, a MPP Solar LV2424, and 8x 272Ah LiFePO4 cells for storage, to run my server rack, and hopefully bring the electric bill for my workshop lower than the one for...

I'm setting up a solar system in my workshop based on the MPP Hybrid LV2424. The inverter is here, most of the wiring and other components are here, the panels will be here in a few days--but the batteries have yet to even get onto the slow boat from China. Is it possible to use this device...

I'm considering building a system around a LV2424 inverter for use in my shop. As I read the manual, I see it calls for overcurrent protection on the grid input. However, I don't see anywhere in the manual a specification for max AC input current. Is it just a matter of making sure it doesn't...

I came here after watching several of Will's videos about LiFePO4 batteries, thinking about re-powering a fairly large UPS with LiFePO4 batteries rather than SLA. But there are some technical concerns with that, I saw the thread about the XUBA 280Ah cells, this led to that, that led to this, and...

For background, see this thread: https://diysolarforum.com/threads/lifepo4-for-ups-battery-replacement.6127/ tl;dr: I'm wanting to assemble a 24v LiFePO4 battery pack of around 20 Ah capacity to replace SLA batteries in a UPS. I realize this is quite a bit lower capacity than most folks around...

tl;dr: I'm getting annoyed with the SLA batteries in my UPSs, and thinking about replacing them with LiFePO4 packs (either preassembled or DIY), mainly for increased life span. I have two UPSs that are in need of batteries. For those who aren't familiar, UPSs typically use packs of 12V, 5-9Ah...
