I am experiencing major issues with the Charger 2. To me, it looks like the current firmware version (v30041.01.17) is extremely buggy.
The following issues have been identified:
1. PV power is extremely unstable and fluctuates heavily.
2. A connected B230 triggers the error G053 – Pack Undervoltage.
3. Auto Sleep: The system does not automatically switch the System Switch back on once PV power becomes available again.
Regarding issue #1, I have observed the following:
PV power output remains very low, even though the connected power station is not fully charged. However, when I connect my B230 to the BAT port, PV power suddenly increases significantly and becomes fully available (despite the G053 error). The full power output remains available even when the B230 is turned off.
If the power station connected to the CHG port (in my case, an Elite 400) becomes fully charged and its AC output is enabled, PV power starts fluctuating heavily again, even though the AC output power remains constant. Only when the AC output power drops to 0W does the Charger 2 regulate properly and reduce production to a maintenance level of approximately 6–7W via the PV input.
Regarding issue #2:
This issue only occurs with the B230. If, for example, I connect an AC200MAX to the BAT port, everything works exactly as expected.
Regarding issue #3:
So far, I have observed the following: When no PV power is available anymore (at night), the Charger 2 eventually switches the System Switch to OFF. Unfortunately, it does not automatically switch back ON once PV power becomes available again the next morning
