FAQs

Q: RES does not start up with ONLY PV connected.

A: Please make sure the voltage of PV is higher than 125V. If everything is ok but problem persists, please contact Dynastorage local technical service center.

Q: SOC changed after restart the system.

A: When restarting the system, SOC only depends on the battery voltage. After a whole charging and discharging process, SOC will be accurate.

Q: Battery cannot charge to 100%

A: Battery will also stop charging when battery voltage reaches charge voltage set on Dynavolt APP, check the setting of APP.

Q: The inverter displays off power grid or utility loss.

A: If there is no voltage on the AC side of the inverter, please check below items: Whether the grid is off Check if AC breaker or other protection switch is off; If it is the first installation, check if AC wires are well connected and null line, firing line and earth line have one-to-one correspondence.

Q: The inverter doesn’t work or the screen has no display.

A: Please check if there is DC power from PV panels, and make sure the inverter itself or external DC switch is on. If it is the first installation, please check if the "+” and "-" of DC terminals are connected inversely

Q: Does the inverter need to be earth ground?

A: The AC side of the inverter is force to earth. After the inverter is powered on, the external protection earth conductor should be kept connected.

Q: The inverter displays off power grid or utility loss.

A: If there is no voltage on the AC side of the inverter, please check below items: Whether the grid is off Check if AC breaker or other protection switch is off; If it is the first installation, check if AC wires are well connected and null line , firing line and earth line have one-to-one correspondence.

Q: The inverter displays the insulation resistance value of PV panel to earth is low or ISO Failure

A: The inverter detected the insulation resistance value of PV panel to earth is too low. Please reconnect the PV panels one by one to check if the failure was caused by a single PV panel. If so, please check the PV panel’s earth and wire if it is broken.

Q: The inverter displays PV panels’ voltage are too high or PV overvoltage.

A: The inverter detected PV panel input voltage is too high. Please use multi-meter to measure PV panels’ voltage and then compare the value with the DC input voltage range which is on the inverter’s right-side label. If the measurement voltage is beyond that range, then decrease the PV panels quantity.
