I have an Multi RS Solar running my home as a backup for heavy loadshedding (18-20 hours at a time!). System is performing great, and before midday my Pylontech batteries are fully charged. I would like to try have the excess power generated during the rest of the day channeled to heating a 1500W Geyser. If the solar is insufficient, it should revert to using the Grid to heat the water. Just means i'm not wasting excess solar when it could be used to keep the Geyser somewhat warm to hot... I'm guessing this would be done through the AC2 Port, but with the lack of a fully functional ESS on the Multi RS Solar, just wondering if that would be possible, or if there is another way to do this cleverly?
