+ | Please note that when enabling this option, the DVCC charge current limit configured under Settings -> Limit charge current won't be active. The Solar charger will operate at full power for maximum feed-in into the grid. It's advisable to configure a safe limit on the solar chargers when used with a small battery bank. | ||

The same applies to other solutions where the wiring is not protected against accidental removing, for example a simple cable with end-user removable plug, such as a portable power supply. | The same applies to other solutions where the wiring is not protected against accidental removing, for example a simple cable with end-user removable plug, such as a portable power supply. | ||

+ | ===== Troubleshooting ===== | ||
+ | |||
+ | - Start with checking firmware versions (needs to be latest). And when asking questions; report the exact firmware versions that are used. | ||
+ | |||
+ | - Check battery type/brand. If lead then it might be unsuitable and probably broken because of the heavy cycling. | ||
+ | |||
+ | - If some unknown or unsupported CANbus battery; change the battery to a supported type. | ||
+ | |||
+ | Then; if PV is not used enough to power loads; | ||
+ | |||
+ | - Check for the # reason codes; see CODE KEY in this manual. | ||
+ | |||
+ | - Check wiring: lots of voltage drop between MPPT and multi will prevent the system from effectively powering AC loads from solar power. | ||
+ | |||
+ | - Test with and without SVS enabled. | ||
+ | |||
+ | - Next, check MPPT charge current limit during the time that it is not used enough. MPPT CCL is supposed to be high always; even when battery full. Unless there is a temperature issue. | ||
+ | |||
+ | - Now check MPPT Charge Voltage Setpoint. It is supposed to be above actual battery voltage. | ||
+ | |||
+ | |||
+ | Note that those last two setpoints are determined by software; and calculated based on the setpoints sent by the (CANbus connected) lithium battery: you can't change change them manually. Looking at them however does help understanding why certains things are happening; | ||
