Batteries are charging by utility even though I have option 16 set to "solar only". This is causing me to waste excess solar energy during the day that should be battery stored because the utility has already charged the batteries from the overnight discharge/charge cycle. It appears that option...

Hi. I finally got 8 panels racked and working. I chose 4x6 posts sandwiched by 2x10's with horizontal struts. I plan to duplicate the rack for the next 8 panels. How is your system performing? by the way whats your name?

Hi. Nice job on the rack. Im considering this option. Do you have any issues with corrosion where the steel unistrut makes contact with the aluminum panel frames? what did you use for grounding connections to your panels?

Good ideas. I do the same things sealing the posts using gravel for drainage but I hadn't thought about the sontubes.

Thank you for all the detailed information. This forum is really helpful. I think I'm going to build something similar to yours. I was making it too complicated. Its cheaper and easier to add more panels than pay for an elaborate adjustable racking system to squeeze out a marginal amount of...

Hey I was looking more closely at your ground mount. Did you use actual unistrut or the generic stuff like you get at lowes? what did you use for the strut end to end splice? What clamps did you use to attach the panel?

I have 8 batteries. they are the SOK 12v 206A units. So two 48V 206A packs in parallel. No issues with them. If the grid fails they kick on instantly and will run my house up to 24hrs. I dont even notice when my power goes out unless the batteries were to completely discharge of course. Thanks...

Hi sorry for the late reply. Yes I have 21Kwh capacity from my two inverters. Its more than enough for my home. Im typically loading at about 10% except when the electric dryer runs Im at 30%. Will reevaluate with the AC this summer. Yes I will have 4 panels in series per pv input. That should...

Hi I have the same Aptos panels. Havent installed them yet. How are they working out for you?

Hi thank you for your comments. Its my first build so I'm learning as I go. The batteries are SOK 12v 206A. I have 8 configured for two 48v banks. The two inverters allow me to have split phase 240v power. 1 inverter per phase. The outside panel is a 200A cutoff which becomes my main panel...

Im looking at these also but the ground clearance is a concern. If you install as they recommend with 50cm square x 85cm deep concrete piers - that comes to 12 80lb bags of concrete per pier (4x) and that only gives you 2.8" of ground clearance fully tilted to 45 deg. Other than that the design...

MPP LV6548 48v Splitphase 240V Hybrid (grid assist) build. Just sharing my build to date. Presently its a whole house battery backup system. Next I need to install the 16 440W Bifacial ground mount panels. Considering 4 of the EG4 brightmount systems. Im in a residential area. The panels will...

Hi Bentley. Thank you for your advice! About the critical balancing step, I connected all 8 in parallel and charged them (power queen 14.6v 20A LIPO4 charger) all fully - it took about 3 days. The next day (maybe 2 days later) I connected them into the two 48v banks. The two banks should but...

I have 8 SOK batteries made into two 48v 206A banks. I'm feeding two MPP lv6548 inverter/chargers to power my home. Essentially the system for now is operating as a whole house UPS (ground mount solar panels will be installed in the spring). Everything appears to be working so far.. My...

Good point i was thinking of putting them near the inverter but i need to remember the wires are a system component thats not cheap or easy to replace. Any recommendations on breakers or fuses? thank you!
