Full video:    • Earthwise contacted me for a warranty...  

My earthwise products Solic solar diverter was taking power from the grid when it was active. The Solic unit should maintain a neutral load on the grid, i.e. it should not allow power to come or go from the grid when solar is producing a surplus and should only divert the surplus to the immersion heater. Earthwise Solic saw my previous videos and got in touch to help, I returned the unit and they updated the software (I think). I reinstalled it today and it seems to be working properly. Perhaps it is better now, I originally didn't expect it to work with the Victron Multiplus 2 Inverter Charger, but the upgraded software (Firmware?) now works to favour the charger so both can work alongside one another. This is a bonus for me, I originally planned to have just the solic, but when cheap batteries became available it seemed like a good idea to change to batteries. At that point I abandoned the Solic 200 and wasn't thinking much about it until Earthwise contacted me.

I was told that the updated firmware (?) was put in place in summer 2023 around the time that I bought mine and that it:
1. delays start up for 10-15 seconds.
2. unit increases power 8 times slower, and,
3. runs at 0-3% of the threshold, (I think that this means that it will "waste" 0-3% of the excess solar power) but I welcome correction!).
These changes are supposed to make it work better with inverter chargers. I expect to post an update on how the two units work together once spring arrives and the batteries are in normal operation, they are in "keep fully charged" mode at the moment.

I asked what may have been wrong with my unit, the short answer was that it may have been a defective unit and that it is not possible to test them all before sending them to the customer.

There are lots of rules and regulations when dealing with solar, you should heed them. They are probably different depending on where you are.
