Howie,
SimpliPhi also has the benefit of adding smaller KWhr
batteries (3.8). They have a ten year warranty but also say:" AmpliPHI
and PHI batteries’ /expected/ cycle life rating is 10,000 cycles when a
maximum of 80% DOD is maintained"

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
