BATTERY MAINTENANCE AND SAFETY
Battery Maintenance
Battery terminals require frequent care and maintenance. Very high current (up to several
hundred amps), is drawn by the inverter when starting electrical motors and other high
powered appliances. We recommend an inspection of the batteries and the interconnecting
cable connections once every 1-3 months or as recommended by the battery manufacturer.
1. Regularly check all connections; make sure they are always tight. Battery terminals are often
made of soft lead which will slowly compress over time eventually causing loose connections.
2. Check all connections are free of corrosion. Remove any corrosion and coat the terminals
with vaseline or grease to help prevent future corrosion.
3. Take specic gravity or SG readings of each cell using a hydrometer to check the level and
performance of each battery. Alternatively a battery voltage reading for each cell will suce
but may not be accurate for multiple batteries connected in parallel. Report any serious
imbalance to your system installer or battery supplier for corrective action.
