SRNE 20KW parallel ASP journey.

I just got back from China yesterday so today is my first chance to open the inverters. So far everything is looking really good. I’ll update as I get them installed this week.

Is there an srne cheat sheet somewhere that delineates the models and their abilities/pros/cons?

I think there was something floating around a while back but newer models would make it obsolete.

What comes to mind quickly.

HYP - basic 5kW single phase, can be paralleled for split phase. Has AC input breaker.

ASP - basic 10kW split phase, can be paralleled (* 3 phase attempts did not work well). Dual 22A 5500W 500VOC (~425 working volts) MPPTs. Has AC input breaker.

ABP - slightly upgraded ASP, has additional breakers built in.

HESP - fancy grid interactive, not a very high pass through.

HEBP - fancier grid interactive with a high pass through.
 
That 12k unit I have would probably be ideal because of how small it is as far as fitting it on the wall. But with 3 inverters I'd want one of the 24k ones I have but you may now have enough wall space for that one.

Being inverter style units the 24k doesn't normally use any more power than the 12k surprisingly across an entire day of use.
Fwiw, Sams Club had/has a 12k window AC, Inverter, Midea, not the U, on sales for $249.

Found some decent inexpensive parts on Amazon for my busbar setup. This will be for the 2 Inverters and 4 batteries to start.

Panel
Bus Bars
You need to drill the bars and ensure those are copper and not brass. Second, the base has to be solid and the studs held well in place. More than one member bought busbars off Amazon and found the bars were brass and the studs heated up and pulled out of the base.

The 600A busbar shown here was recommended by another member here. It is copper, I drilled one. It is built well. It is on Amazon.

Agreed, I have tested. They are tinned copper just as described.
 
Last couple days have been crap, fortunately the high sun angle and minimal HVAC needs have helped keep the bank relatively flat.

On a positive note, just over 12MWh through the pair, still flawless.

I've been running the shop heat pump non stop for a few weeks now. I need to get the second heat pump installed. The past week was the highest yield I had yet from the 8.8Kw of panels. 282 Kwh for the week.

I wasn't able to enjoy the cool shop over the weekend, busy taking down more ash trees. Not fun with hot and muggy weather. Weather forecast was for cool temps. Somebody lied. Only one ash tree left. I think winter at -10°F would be a good time to cut it down after this weekend.
 
Weather has been kicking my butt this month. I have been running the eco-worthy 60 amp charger off the dryer outlet nearly daily to keep things going. Can't get any decent production between rain and clouds. I was so looking forward to spring/summer to see what all of the panels I had added could do but its been pathetic so far because of the weather.

Lots of thick smoke from the wildfires out west has made the midwest very hazy even on "clear" days.
 
It rained the last few days, showers on Saturday, then poured overnight. Sunday night into Monday rain again and clouds all day yesterday.

Today would be sunny but the sky is white. One would think that crap would wash out of the sky at some point. And Canada would run out of fuel to burn. There must be bad management of forests in Canada.
 
so my paralleled units which essentially is the same as this, I keep getting inverter cutouts once a day in the afternoon, likely when all my AC units are running.

I saw what I believe to be error 30 flashing on both the other day, but havent had time to track down the issue. the amp and watt pull is not exceeding the inverter capacity, but I believe i am somehow undervolting in some way on the batteries.

any thoughts?
