Setting 5 on my SPF-6000t-DVM growatt has to be use, not us2, had that problem in the beginning, Joe.I finally got the SPF 3000TL LVM-ES about two weeks ago.
The fan on small loads is really not that bad. I'm happy so far.
One problem: After wiring up the batteries and panels, I turned on the unit and everything started to work properly. The batteries came to 100% SOC within a few hours of sunlight. Overnight, I used about 10%-20% of the battery capacity, which is expected. The next day, I was hoping the Growatt would start charging up the batteries automatically when the sun is high enough. I waited until 11am (full sun) but still 0 amps going into the battery. The panels show 180 VOC. So I decide to turn off the Growatt with the little button underneath the unit, wait a few seconds and turn it on again. Then the batteries start charging! What happened? It makes no sense to manually start the charging process.
Any clue?
