BATT LED Behavior Protection
Cause / Fix
The controller is detecting a low battery voltage and
alerting the user
1.Use a multi-meter to check the battery reading
and verify whether the LED matches your intended
battery type and voltage. If the battery is low,
disconnect any loads and let the battery charge for
an extended period.
The Rover Boost is equipped with electronic protections to protect the controller and the
system. If the Rover Boost is not functioning correctly, it may be undergoing an internal
electronic protection. This is not indicative of a defective controller but may require some
troubleshooting to resume normal operation mode.
The Rover Boost has the following protections: battery undervoltage warning, battery
overvoltage, battery over-temperature, battery under-temperature, battery reverse polarity,
battery open circuit, PV reverse polarity, PV overvoltage, PV short circuit, PV Power Limiting,
back-flow protection, and controller internal over-temperature.

The battery has discharged below the under-voltage
warning and needs to be recharged. The controller has
stopped charging utilizing the electronic protection and
may have disconnected from the system.
1.Use a multi-meter to read the battery charging
voltage and verify the voltage is within the battery
charging parameters seen in Technical Specifications –
Battery Charging for your respective type.
2.Disconnect any loads from the battery and ensure
your panels are working and let the Rover Boost
charge the battery.

The battery is connected to the controller but not
charging or not detected. This is a protection for
non-lithium batteries. Extra caution must be taken
with Lithium batteries in reverse polarity. This may
cause irreversible damage to the unit as a reversely
connected battery may be interpreted as a
discharged battery and undergo Lithium Activation.
1.Use a multi-meter to verify a battery voltage as well as
the battery voltage being within a 36V / 48V system by
comparing your values against the Technical
Specifications –Battery Charging, for your respective type.
