The Rover Boost is only suitable for 36V or 48V battery banks only. Not abiding by
these battery voltages may lead to irreversible damage to your controller or system
The positive or negative battery cable should be protected by a fast-acting fuse or
circuit breaker of 15A-20A, rated for the maximum battery voltage and connected
close to the battery terminal or power distribution block. This fuse will protect the
wiring in the event of a short circuit or controller damage.
Locate the OUTPUT side. Expose the positive and negative battery output terminals by
unscrewing the M3 screws holding down the removable battery output cable housing.
A small spark while connecting the battery to the controller is ok. However, make
sure to have appropriate wiring at the input and output.
The M3 screws have a recommended torque of 0.5~0.8 Nm / 0.4~0.6 lb. ft. The
M6 screws have a recommended toque 4.1~5.0Nm / 3~3.7 lb. ft.
Be careful with the positive and negative poles of battery bank; reversing them or
having them make contact may cause irreversible damage not covered by warranty.
WARNING
The Rover Boost has reverse polarity protection for battery connections and extra
precautions must be taken when connecting Lithium Batteries. Do not have a PV
Source connected until the correct battery setting has been selected.
WARNING
NOTE
NOTE
The Rated Max PV Input Power is 500W (36V) or 650W (48V)
NOTE
Larger wire sizes will improve boost performance whereas smaller wire sizes will
reduce boost performance. When considering wiring, fuse, and connection options
think big and short as larger heavier components and shorter wire lengths offer less
resistance and voltage drop.
