Thats a cooling climate since we are actively cooling more than heating. If you have more cdd65( cooling degree days) than hdd65 days then you are in a cooling climate. You can still have passive solar in a cooling climate though. Just face the largest windows towards the south and provide...

Raise it more! Charging at 1c for 10 minutes is not going to hurt your battery. We need to know if that's the issue

Its on the sunny island side. If the battery is not full, ie not to target voltage it should be charging at full allowed capacity so if it's not it's because the sunny island is throttling output. Check your frequency. It should be 59.99 or 60hz. If it's higher than that it's throttling output...

If float is 2.3 that's 55.2v Did you increase battery charging amps? Do you have your battery set to 23 cells or 24?(46v or 48v)

Turn afra enable off. I think the sunny island will not output power at 58.9hz. If you turn afra enable off frequency won't go below 60 and you should start charging again

radiant barrier doesnt work if something is touching it so you might as well skip it for the walls. sounds like you are in a cooling climate, not heating

So set it to 140amps then. 50a is too low. Do you have a way to measure frequency? A multimeter or something? When the sun is max test your frequency and see if it's higher than 60.00hz

I would bet that the system is throttling your sunny island hard. 50a battery charging current is only about 2.4kw. change that to 300 for now and please let us know what happens

I haven't heard anything so far.

Additional questions. What do you have battery charge current set to? How about ac charging current?

If you will have any 120v loads on the 230v inverter you need an autotransformer. If it's only the mini split then you don't. I bet you those micro inverters are inefficient as hell. A 5 kw growatt grid tie is $720. 6kw $750. With a micro inverter or any grid tie inverter you have to be...

What pv source do you have? Do you have the grid connected?

Where's the power going?

That's very nice. The pv will shorten the payback period quite a bit. Leave space for more pv as you might get addicted. I started out wanting 3kw ended up with 18kw. How much are they quoting for the work?
