SOLAR LIGHT TRAILER SCHEDULED MAINTENANCE
SERVICE GUIDE
Battery:
Do monthly check on the battery, tighten the battery cable connections as needed. Wear gloves/eye
protection and use insulated tools.
Clean terminal connections & cables to prevent corrosion. Mix baking soda and distilled water into a paste
and apply with a wire brush. Rinse cleaning residue and dry with a cloth or paper towel.
Keep the top of the batteries clean from dust and debris to avoid creating a current pathway or electrical
leakage across the top of the battery.
Program your voltage set points so that the battery bank charges at the proper voltage.
Check Battery State of Charge (SoC):
Use a multimeter to keep an eye on how charged your sealed lead-acid batteries are based on the voltage. A
multimeter is equipped with positive and negative probes which allows the meter to get a DC voltage reading
from the battery.
Multimeters give a DC voltage reading from your batteries.
Look up the battery’s model number to find its datasheet. It should contain a chart that estimates the battery’s
state of charge based on these voltage readings.
To get the most accurate reading, your batteries should be tested in a resting state. Let your batteries rest for
at least 2 hours (no charging/discharging) before taking the voltage reading. Attempting to use the multimeter
when batteries are being charged or discharged is going to result in a higher or lower voltage, depending on
the load.
If your batteries fail to approach 100% SoC even after a full charge cycle, they are likely defective, damaged,
or have reached the end of their lifespan.
CAUTION:
Under no circumstances should batteries be incinerated, as fire can cause an explosion. Wear approved
gloves when touching electrolyte. On exposure to skin, flush with water immediately. If eye exposure occurs,
flush with water for 15 minutes and consult a physician immediately.
