JayMc got a reaction from drzoidberg33 in Solar geyser losing heat at nightJust saw that I never posted an update on my installation. I had significant heat loss at night and also installed a NRV. Solved the back feeding problem and was very easy to do.
Green = geyser at hot outlet side.
Yellow = solar collector temperature at the inlet side
Blue = Temperature at the collector on the output side.
During the night, there appeared to be back feeding of water into the collectors (blue). Once that NRV was installed, that blue line drops over night which means there is no longer a back feeding of hot water into the collectors.

JayMc got a reaction from zsde in [SOLVED] Growatt SPF5000ES USB B port not working (?)Hey!
Ye, my problem started in December 2022 when my SA was giving voltage errors. I changed out the power supply and didn't connect the dots in regard to the communication issues that then started. It was only recently when I swapped the power suppliers back to how they were that things returned to normal. I advised SA of the problem I faced and how it was resolved.
Glad you're sorted too!

JayMc got a reaction from zsde in Solar geyser pump circulation timeI have a split system with 20 evacuated collectors.
I have 3 sensors and all data is brought into my Home Assistant. I have a sensor on the collector output (but I now see it's positioned too far away from the output side), a sensor on the collector inlet side and a sensor on the geyser hot output.
I had the pump running all day but have now created an automation in Node Red to basically toggle the pump. Keen to see how this performs!
