SAFETY PROTECTIONS

SPECIFICATIONS
– Reverse polarity solar and battery connection.
– Against reverse current from battery to solar panel at night.
– Transient over voltage protection, a varistor or transient voltage suppressor (TVS) at the solar
input and battery output against surge voltage.
Remarks: Battery Voltage settings for 12V mode, x2 for 24V mode. *The LI95 battery profile
keeps your LiFePO4 battery charged at 95%. Evidence suggests that charging your Lithium
battery to less than 100% can increase longevity of your battery.
Occasionally check that the wire terminals are securely tightened. Inspect wiring to ensure
nothing is or has become exposed. Repair if necessary.
Occasionally, clean the case using a damp cloth and mild cleaning agent.
