Grid frequency out of range
1. Check the frequency is in the range of specification or not;
2. Check whether AC cables are firmly and correctly connected;
3. Seek help from us, if cannot go back to normal state.

DC busbar voltage is too low
Battery voltage low
1. Check whether battery voltage is too low;
2. If the battery voltage is too low, using PV or grid to charge the
battery;
3. Seek help from us, if can not go back to normal state.
1. It tells the communication between hybrid inverter and battery
BMS disconnected when"BMS_Err-Stop" is active;
2. If don’t want to see this happen, you can disable "BMS_Err-
Stop" item on the LCD;
3. If the fault still exists, please contact us for help.
1. ARC fault detection is only for US market;
2. Check PV module cable connection and clear the fault;
3. Seek help from us, if cannot go back to normal state.
Heat sink high temperature failure
Heat sink temperature is too high
1. Check whether the work environment temperature is too high;
2. Tu r n o f f t h e i n v e r t e r f o r 1 0 m i n s a n d r e s t a r t ;
3. Seek help from us, if cannot go back to normal state.
Victron BMV setup - State-of-charge measurement
The Victron BMV provides the most accurate state of charge measurement of the batteries. It uses a shunt to measure the
current flowing into and out of the battery, rather than just relying on the battery voltage.
For it to provide the correct readings the battery size needs to be entered correctly. This is done in the factory, however if an
additional battery is added later then this value will need to be updated.
In addition, the Victron BMV will need to calibrate itself over a couple of charge-discharge cycles to be completely accurate
after the initial installation.
The procedure to change the Battery capacity is most easily done by using the VictronConnect App.
The table shows the settings to apply for the BlackMax.
Review the Victron BMV manual provided in the Parts kit for additional details.
• 80Ah: One Troppo battery
• 160Ah: Two Troppo batteries
• 240Ah: Three Troppo batteries
Time-to-go averaging period
Battery starts synchronised
Battery SOC after a reset will be 100
State-of-Charge
Manually set the current state of charge
30%. Manually set SOC to initial state-of-charge
(usually 30% from the factory)
No need to synchronise. Can be done if the
batteries are known to be full.
