Solar battery backup for home. Sol-Ark 15k with Stackrack batteries.

Installing best-in-class Sol-Ark 15k with 30kWh battery backup from StackRack.
Connecting 2 PV solar arrays to inverter - AC and DC coupling.

Great job on the setup. The only thing I don't like is the bus bars in the inverter. I wouldn't use those. Instead I would use the 2 cables per side of the battery (4 in total) because of the amount of amps that inverter can push/pull when operating at max. By using 1 cable per side of the battery (2 in total), you're placing a tremendous amount of amps on a single cable when the inverter is operating at or next max.

Those look just like Pytes E-Box batteries. Excellent installation.

[@SolarEngineering]

it is white labeled Pytes batteries. Thanks!

Nice clean work sir Really Good job Peace Prospector Tripp

Хорошая работа, вопрос, а почему жилы не обжать перед подключением? Окисление и неполное прижатие ведь будет при таком подключении…

[@SolarEngineering]

по местным правилам обжимать не надо. Если затянуть правильным моментом, то не должно быть проблем.

[@bluzytrix]

Did you run a cable from the grid through the bottom of the main panel, through the raceway and then to the solark?

[@SolarEngineering]

1:22 at the bottom you can see 2 LBs, a deeper one going from the main panel to AC disconnect and then to Sol-Ark. From Sol-Ark coming back to subpabel via another LB.

hello what are your thoughts on using an Automatic transfer switch versus a double throw switch ?

[@SolarEngineering]

double throw is more like for servicing system, no ATS needed there

[@pharpester]

Using a sol-ark 15k would with generator and no batteries, with no solar, how would you use the Sol-Ark as an Auto transfer switch?

[@paulcarrigg8320]

If you have no solar and no batteries, then when you install the backup generator you make sure you buy the automatic transfer switch and your down. Power goes out, transfer switch senses power outage and stars generator. When power comes back, it’s senses that and turns off generator. 25kw with transfer switch might be about 7-8K?

[@pharpester]

That is what I was thinking, but I want to use sol-ark as the Auto transfer switch until I can buy batteries. Otherwise in your example I am spending $1k for transfer switch, the. When I go to get a sol-ark 15k, I throw away that $1k.

[@TKO67]

where do you get those bus bars ?

[@SolarEngineering]

I'm buying it from online stores, just search for "solark15k busbar". Price range $50-$70

[@TKO67]

@@SolarEngineering thanks, excellent idea

[@quickquote1568]

I would never install a Sol-Ark as a backup power source for my home because it doesn't offer a high enough surge power capacity for the loads in my home.

[@SolarEngineering]

are you aware of any alternatives?

[@quickquote1568]

Yes, Schneider Electric, Sigineer Power, Outback Power, and Magnum Energy all offer heavy duty, high quality transformer based inverter chargers. Watch "XW Pro vs Sol Ark" to see a comparison between these two inversion technologies. @@SolarEngineering

[@solarcharging9743]

Yes, the Schneider Electric low frequency XW series inverters or the larger Sigineer low frequency, transformer based inverters.
