After three shut down and restarts, followed by a low battery shutdown within 30 seconds of restarting, the inverter will shut down
and stop retrying based on the low battery restart level. To override this and restart the inverter, switch it Off, and then On, and
limit loads to enable recharging of the battery with solar energy.
See the Technical Data table for default low battery shut down, restart and charge detect levels. They can be adjusted with
VictronConnect (computer or app).
Additionally another external MPPT or battery charger can also be used to recharge the battery to reach the Restart Voltage or
Charge Detect voltage level. !!! If using the allow to charge signal functionality, it must remain above the minimum voltage, so if
the battery is completely dead it will not allow charging to start. In this case, you can temporarily disable this function in
VictronConnect to allow charging to resume, then enable it again.
See the Technical Data table for default low battery shut down and restart levels. They can be changed with VictronConnect
(computer or app). Alternatively Dynamic Cut-off can be implemented, see

5.3.3. High battery voltage
Reduce DC input voltage and/or check for a faulty battery- or solar-charger in the system. After shutting down due to a high
battery voltage, the unit will first wait 30 seconds and then retry operation as soon as the battery voltage has dropped to
acceptable level.
5.3.4. High temperature
A high ambient temperature or enduring high load may result in shut down to over temperature. The inverter will restart after 30
seconds. The inverter will continue to try and resume operation, and will not stay off after multiple retries. Reduce load and/or
move inverter to better ventilated area.
