Question for all you Homegrid installers…has anyone found a succinct way to run
conduit from the battery enclosure to the Sol Ark?

Jay,
I should mention I have a couple of customers with big EG4 LifePower battery
banks (i.e. 120kWh+, 80kWh, etc) and Sol-Arks. The clients purchased the
batteries directly, so I didn't have a choice. I will say that the systems are
performing flawlessly, but forget about closed loop comms and SOC management.
Everything is voltage based, which is suboptimal. But we're making it work. The
Sol-Ark app still reports their version of SOC, which is handy for clients, but
charge setpoints are done with voltage.
Signature Solar has provided pretty good support, but I didn't need much help.
I strongly suggest the Communication Hub to get SOC data from the battery BMSs.
It's pretty handy and very easy to install.
With that said, I don't sell EG4 and don't necessarily recommend it, but to be
fair, I haven't had any problems and the capacity claims seem legitimate. The
value proposition can't be ignored.

Thats all super helpful, appreciate the advice everyone.
I’ve not used the sol ark 15 and just wanted to make sure I wasn’t missing
anything about battery options.
And specifically the ones that don’t seem to play well.

HomeGrid works great with Sol-Ark. Closed loop comms reports battery SOC from
BMS. Parallel stacks install easily. Customer support is competent and patient,
in my experience.
The best part is the ability to easily add batteries. On Sunday I had a client
with two stacks of five batteries each call me in a panic ahead of Hurricane
Milton. He wanted more capacity. We had them in stock. On Monday my team added
three batteries to each stack on the fly since we couldn't do a roof install
that day due to rain. We had it done in about 2 hours, and that included moving
the stacks due to a height conflict with a piece of equipment.
And now, 48 hours later, I'm looking out my home office window at the trees
bent over. A tornado passed close by a few hours ago, debris pelting my
windows, and a neighbor lost their lanai ceiling. Too close for comfort! But I
have power, at least. :)
Wish us luck.

We’ve been installing the Tesla power wall 3 and have had zero issues, a very
robust product, downside is no generator support.

2 – Homegrid both required quite a bit of programming assistance not everyone
who answered the phone was knowledgeable enough to get the fixes installed.
2 – Pytes fired up fine no issues.
2 – Solar Edge both required assistance, quick & simple fixes with Tech staff.
I have a client who has started off with “I want Tesla batteries” how has Tesla
batteries faired on installation?
