Sol-Ark pushed an update to my 12K last night. Yesterday it was overcast and my system produced ~10kW, today was super clear and sunny and it produced ~4kW. Here are the graphs of the Solar production from the 2 days. It seems like something is up. They are trying to blame the EG4 Communications...

I found that my local Platt dealer was willing to sell to me.

I'm considering using the new Sol-Ark optimizers on a new build. It looks like they use 48V off the battery terminal to produce the permission to operate signal. I'm thinking through different ways to provide the 48V to "Dark Start" the system in case the batteries are drained and the grid is...

@HighTechLab Do you know when the new pricing will be in effect? Looking to buy a 12k and optimizers soon.

I would put the 7s on their own MPPT, but the Sol-Ark 12k only has 2 MPPTs and I figured putting each roof area on an MPPT would be best.

Any advice on this?

I asked for a quote from Greentech Renewables and got this response: "Thank you for reaching out. Greentech Renewables is no longer servicing DIY leads in your area. I have sent your information to our partner, Tandem Solar. They can help you out with all of your solar needs!" I reached out to...

I posted this in the Beginners Corner but didn't get any responses, so I'm trying here as well. I'm looking at getting a Sol-Ark 12k and 24 - Solarever 410w panels. I have 2 roof areas, one can fit 14 panels and the other 10 panels. I'm thinking of doing 7S2P on one and 10S on the other going...

I'm looking at getting a Sol-Ark 12k and 24 - Solarever 410w panels. I have 2 roof areas, one can fit 14 panels and the other 10 panels. I'm thinking of doing 7S2P on one and 10S on the other going into separate MPPTs, the 12k has 2. I put the layout into the Sol-Ark sizing calculator and it...

I'm trying to find racking for my installation, but I can't find anyone local that will sell to me, they only sell to contractors and shipping is too expensive to buy online. I was initially looking at IronRidge XR100, but I'm open to options if I can acquire them. I'm in WA, thanks.

Do you have a link to the switch you used? I'm looking to do the same thing.

Is it necessary to have the relay if the CCA is powered on the load side of the inverter? if you close pins 11 and 12 and the Inverter shuts down that would turn off the CCA and shut down the modules, correct?

Yeah, I looked at the 15k with 200A bypass, but I won't have enough solar for the whole house and didn't want to have to play the breaker game when the grid goes down, so I downsized to the 12k with a critical loads panel.

I'm working on calculating the loads, I'm ordering an Emporia Vue soon to dial it in. I currently run these loads of a 5300w generator though. 1.5HP well pump, refrigerator, lights, internet. Just backing up a critical loads panel, not the whole house. It does need to be UL listed.

I'm looking at installing a new solar system with about 10kW of panels, batteries (probably EG4 LifePower4), and a generator. This would also be grid-tied with 1:1 net metering. I like the all-in-one concept and am going back and forth between the EG4 8k and Sol-Ark 12k. Obviously, the big...
