How to expand the solar panels
Note:
CAUTION: Risk of damage to battery pack
Connecting solar panels in parallel up to 240W for a 12V/24V system is a
recommended solution to speed up the solar charging time. The open circuit
voltage (Voc) of the connected panel should be between 14VDC - 63VDC and
the maximum output current is limited to 20 amps. So mostly every panel
can be used.
Using multi plugs to parallel connected solar panels is recommended.
The current of outputs that exceeds 20 amps will interrupt the fuse.
Polycrystalline or monocrystalline modules for in 12V/24V system could be used for
charging MJI-1500-01. Any other panels used in higher voltage system (over 63VDC) or
amorphous modules can damage the battery pack.
