Good info. In this case the setup was pretty straightforward with voltage settings at the charge controllers(56.8 bulk/absorb, 54 float, 48 cut off programmed at the inverter) The real-time current discharge and AH clocking in and out on the display is handy for the power picture. The system...

Schmism, the homestead's power demands will grow as I build and 12kw will be needed before too many years. The inverters can be stacked, but I'm hoping to avoid the runaround getting two inverters to play nicely for a few years. The 12kw Sol Ark was in the budgeted range and I was hoping the...

Rocketman, my biggest hurdle with the DIY packs is selecting a reliable BMS manufacturer. Any thought on this and the best supplier for genuine EVE cells? They seem to be leading the value range of the LFP sector. I'm comfortable with the technical aspect of it.

Thanks to each for your input. I've moved to purchasing and plan to update once the system is running a while. The Trophy batteries with integrated BMS and EVE cells offered a great value for the price. Manual disconnects for the PV and batteries, the 48V system cuts the current rating needed...

To summarize so far: 48v sounds like the choice for higher kilowatts, and yes this definitely has the potential to grow into a future house build. Currently powering a camper and 18k BTU AC unit, but I may step up the inverter sizing to 8kw. Starting with my needs and working up. LFP battery...

Still available?

Setting up a solar system from scratch, I've found some great, concise information on here and realized the time has come to quit lurking and post for some specific answers. Batteries: Looks like a Gen2 Tesla 24v battery pack offers the best value used from a low mileage vehicle. Not sure if...

Seems a 100 watt heat lamp in the shed/room on a temp switch set to cut on below 50, for example might be simpler?

Great point; I'd love to go LFP for the stable chemistry. I'll hash some costs on that. Do server batteries offer any charge management or are they a brick of cells? Is there a well priced source for these, maybe 1 or 2 year used swapouts?
