Hi All, I am looking to upgrade an offgrid client's battery bank from 2-volt Rolls KS17s to LiFePO4 batteries. I'm basically looking at one Fortress eVault Max cabinet vs. a HomeGrid 4 stack option. I have used the eVault Maxs before, and generally like them. The 2 options are relatively equivalent cost and size. The advantage of the eVault is that I've used them with good success several times, and they have a better listed warranty (6,000 cycles vs. 4,000, slightly more favorable end of life capacity retention). The reason I am considering the HomeGrid is because the promise of more incremental increases if that becomes a need (4.8 kWh blocks vs. 18.5 kWh) and the promised ease of adding up to another 4 blocks with apparently little or no effort compared to the need for a whole other large battery connection. These will be matched up to an existing Sol-Ark 12k inverter. If anyone has any experience with the HomeGrid (positive or negative), or experience with both brands, I'd love to hear any feedback. I hate installing equipment I haven't used before! 😕 Thanks, Howie
