Dear Community,
we are facing somehow a strange behavior with our Smartsolar 100/20 at a remote location (not accessible for debugging). Initially the system was a 12V system, we re-arranged it to be a 24V system with two PV panels in serial connection and two 12V LiFePo batteries in serial connection. Therefore we set the system setting to 24V via BT connection and the App and re-powered everything (Smartsolar and globallink). Our load should be constant with a load of ~12W. In the dashboard we see a strong variation of the load current with the solar power up to 1A which is more than the double of our load connected to the output. At night, when the load should be fully battery powered (no solar power) the battery current is too low for the 12W load (battery current -0.2 or -0.1A)
We do not understand the load current variation. This seems to be completely off. All connections to the Smartsolar module are directly to the module with both + and - wire. Load is only connected to the load output of the Smartsolar 100/20. Only the Globallink gateway is directly connected to the battery (24V)
I kindly ask you for support.
Best regards,
Andreas
