    SOL Ark 12k install with Tess batterys

    There is 5 ft of walking space in front of breaker panel. Now in front of the sol ark the top cover is built to walk on. 2 by 4 across the top with 1 inch plywood over it and a stair case going up. So is accessible.

    SOL Ark 12k install with Tess batterys

    I do recommend Sol ark 12k. Its super easy to hook up. Manual book shows exactly how to hook it up and where in the breaker panel. Youtube "Sol-Ark Overview April 3rd" Examples almost everything. 12k model can stack units into parallel . 8k model you can't. Gives more flexibility. High efficiency!

    SOL Ark 12k install with Tess batterys

    of course Sol ark is limited to 63 amps on the load breaker or 50 amps if you hook up to gen breaker . Way around this on AC coupling system just add rest on main panel . Yet even if I had a dc system the inverter is still limited to 63a so it wouldn't excess those numbers anyways.

    solardad If your state Code book is Nec 2020 you are required to have DC micro inverters. Which In my case Its better route to do a Ac micro inverter system. First off its takes the load off of the inverter as it acts as a second inverter since DC power is already converted to AC at the panel...

    400kwh a month is huge saving :) I believe hybrid water heater is a must for solar system. It eliminate need of a few more solar panels and batteries. I love how it acts as a mini ac unit on top. keeps utility room at about 64 degrees. Have you checked your electric company on rebates for...

    SOL Ark 12k install with Tess batterys

    Yes they are 12 batteries but a 48v system. Remember if you see 42 amps on your ac side your battery's are converting 48v dc to 120vac ( Plus inverter conversion efficiency ) so you will have about 2x amperage being pulled from your battery bank. I was looking at Growatt inverters before hand...

Reason went with a 72 inch wire trough giving me the option to add a second Sol Ark inverter in middle if I ever need to parallel...

    Sol-Ark 12K with AC coupling

    Sol ark has a auto transfer switch. If batteries get to low (set amount) it switches over to utility for power therefore you won't have your battery bank empty. No human intervention. You don't even need a net agreement with ac coupling system! as it uses CT sensors. Which is very interesting...

    Sol-Ark 12K with AC coupling

    I prefer a ac accoupling system vs dc system since it takes the load off on the inverter. Why? Ac micro inverters already converter your power to 120/240 ac. Example 10kw ac solar array plus a 8kw inverter = 18kw maximum continuum output during the day. Gives you the ability to get away with 1...
