11500 watts of Solar Panels; 2x Powmr 60amp, 1x Growatt 12kva; parallel charging SLA off grid battery array. - Updated

One piece of advice. Insulate your power shed, remove the fan and replace it with a window A/C unit. The Growatt inverter is rated for indoor installation only, in a conditioned space. It's life will be greatly shortened living in a hot, humid unconditioned space like your shed.

100% agree. The window AC unit in one of the pics above is already set to be used for this purpose. Good looking out! Fortunately I’m still In Testing phase and not currently in production

So I decided to keep the temp controller exhaust fan in case of heat buildup. But instead of a window AC(too much hassle) I got a slick stand up 8000 btu AC. We will also paint the shed reflective white and use foam board insulation on the inside roof and areas I can get to.

Whatcha think?

Added 8000 BTU AC to keep the house cool. Routed the hot air fans to the emergency exhaust fan. Seems to be keeping the hut at 85. Gonna keep testing until I feel confident it won’t get too hot.

The indoor A/C units take an efficiency hit since they draw cool air from the room to cool the condenser plus you have to deal with emptying the condensate container and exhausting the hot air. I don't see an exhaust from the A/C unit? I'd get rid of the standup unit and install that window unit instead as it will exhaust the hot air outside along with all the condensate. Much more efficient.

Sorry the photos didn’t show the exhaust vent and water pipe. They were both installed.

So I have been hooked to the house for 3 days no problems. Getting ready to plan the soft starter to protect the air conditioner.

Current appliances supporting my config

1 x 20amp fridge.
1 x 15amp washing machine
1 x 30amp 240 stove
Full living room lights(30)
Fans 4
TVs 2
Security system
Wifi
Gaming PC

If we see a hurricane 2 x Windows ACs

At this point I’m hooked. Now I’m going to hire a tree trimming company and fill the second half of the tennis court and power the other half of the house.
 
Watching power bill decrease daily. May monthly total was $469. New estimated June payment $397. Using an additional 20$ a month on a separate meter to keep my shed cool.

If I keep the average daily use to 10$ a day I can get this bill down to $320 a month.

Working on getting a second transfer switch into my other panel to power the second side of the house.

Can't the solar run the little Aircon ?
 
For fun I decided to test hurricane window AC with 2 bit coin miners on solar lol

Any clues? Extended time running full power? Temperature/humidity environment?
You added A/C - did that control humidity, or did the fan opening allow humid air in?

There is some equipment designed for hostile environments, sealed or conformally coated. Moisture on a high voltage board is a bad thing. Keeping things cool could be worse than letting them be warm, if humid air gets in.

No clues yet. It still charges the battery but the inverter has failed. The hut is sealed and humidity is low. If I were to guess i might have lowered the life initially testing it without proper cooling. I will be opening the cover soon to take videos for possible warranty board replacement.
