I had four Pytes V5 batteries installed in the V-Box-OC in my garage. :)

This post was about Sol-Ark failures. Can we get back to the original question?

Got this notice in PowerView today.

The reason why this argument goes on and on is because Sol-Ark cut a deal with Deye for exclusivity in the USA, cutting off a cheaper solution for the DIY community. I don't know who developed the technology, but why does it matter. Enjoy your new EG4 like I enjoy my new Sol-Ark 15K.

I've been through both New England ice storms of the last 26 years for a total power outage duration exceeding 15 days. I now have a standby generator, but it consumes propane faster than they will deliver it. I keep hearing how weak the electrical grid is. That's my motivation, but it's nice...

My first system generated a credit in April and May. The second system was a $6 bill in May. The flat rate charge is $16, so it covered all KWH charges.

Engineer 775. I've watched many of his videos.

Also be aware of where the batteries can be located in a garage.

Batteries on a Sol-Ark are a fraction of the cost of batteries with Enphase.

I finally saw with my own eyes; the CCA green LED was off and the TIGO monitoring showed no data for a 5 minute duration at that time. Someone on Reddit said they had my issue, only worse, and it was a bad TIGO power supply. I have another power supply, but I'll wait for input from my installer...

I'm not prepping for an EMP event or any other event that may take the grid down for 6 months or more. I'm prepping for the next ice storm. I've already been through 2, each resulting in lost power for more than a week. We installed a standby generator after the last one. However, we'd be lucky...

Thank you for your input. I think you are being overly conservative. This generator has powered 3 mini-split heat pumps (total 70,000 BTU), plus home loads for 2 homes without fail. I'm interested in the ability of the Sol-Ark to stay locked on to the varying frequency.

Yes, you need to check "charge" for all time slots that you would require Gen charge. Your Start % at 10% is really low. This number needs to be higher than your Discharge Shutdown %.

Out of the box Generac air cooled generators aren't wired for 2 wire start. See attachment for wire modification and programming.

I have them on a new Sol-Ark installation. Today was a good sun day, but this time of the year I have a lot of tree shading. The TIGO monitoring reports total production and reclaimed energy. Today production was 14.81 KWH with 3.97 KWH of that being reclaimed energy. I'm not saying this is...

I was initially investigating potential arc fault issues, but now the focus is the TIGO optimizers dropping out for 5 minute durations. The optimizers don't use PLC. The CCA communicates with the TAP on the roof over RS485. The TAP communicates with the optimizers wirelessly. I am using the...

I was frustrated that Gen Peak Shaving is no longer supported, but then realized what I was planning to do probably isn't practical, that is charge batteries on 3 separate Sol-Arks at the same time. Instead I'll just use TOU to stagger charging of each battery bank. Gen Peak Shaving would be a...

The Sol-Ark is UL listed, meaning it's been critically tested to carry and switch 200 Amp. You can have faith in the 200 Amp rating.

What did I say that sounds like whining?

Check with your fire department. Rapid shut down is for their benefit.

Here's one made in USA.

TIGO optimizers don't communicate on the PV wires. The CCA communicates over RS485 to the TAP and the TAP communicates wireless to the optimizers.

I'm on grid so that's not going to work for me. I want to charge from my generator, but not from the grid. This sounds like a bug. What firmware are you on? For the 15K current version is M7.2.2.2

When the inverter and battery are UL9540 listed together and the installation instructions show spacing less than 3' then it's a permitted exception.

My first interest is the higher 100 A discharge. Four E box batteries only gives me 10 KW. I want to utilize the full 12 KW capability of the Sol-Ark. The heater is just insurance for me. The batteries will be in an attached garage with the only external wall being the garage door wall. I don't...

I don't plan to open the switch with current flowing. Even Sol-Ark warns not to open the built in battery breaker with current flowing.

No, I need UL9540 for AHJ. My power demands will be higher in the summer with A/C. For a winter power outage I turn off the heat pump and run my propane fired hydronic system. I have a combi-boiler.

Everything you need to know should be here.

Not yet. When Sol-Ark releases their optimizer, they will update the MPPT board to include SunSpec PLC.
