4.0 Maintenance and Troubleshooting

The following information is provided to help you keep your MS Series Inverter/Charger in optimum

operational condition.

4.1 Recommended Inverter and Battery Care

The MS Series inverter/ charger is designed to provide you with years of trouble-free service.

Even though there are no user-serviceable parts, it is recommended that every 6 months you

perform the following maintenance steps to ensure optimum performance and extend the life of

your batteries.

WARNING: Prior to performing the following checks, switch OFF both the AC and

DC circuits.

Visually inspect the batteries for cracks, leaks, or swelling - replace if necessary

Use baking soda to clean and remove any electrolyte spills or buildups

Check and tighten all battery hold down clamps (if applicable)

Clean and tighten all battery terminals and connecting cables [10 to 12 ft lbf (13.6 to 16.3

N-m)]

Check and ﬁ ll battery water levels (Liquid Lead Acid batteries only)

Check individual battery voltages (load test those that have a voltage difference of more

than 0.3 VDC from each other) - replace if necessary

Check all cable runs for signs of chaﬁ ng - replace if necessary

Check the inverter’s cooling vents - clean as necessary

Check and tighten the inverter’s internal AC terminal block connections [16 in lbf (1.8

N-m)]

4.2 Storage for Mobile Installations

When placing the RV, boat, or truck into storage, it is recommended that you perform the following

to ensure the system is properly shutdown (or properly conﬁ gured for storage). This is especially

important for maintaining the batteries.

Perform the recommended maintenance steps listed in Section 4.1.

Fully charge the batteries.

Connect AC power (if available) and verify the breaker to the inverter’s input is switched

ON (to allow battery charging).

Verify the inverter is switched OFF.

Switch OFF all unnecessary AC and DC loads.

Disable the AGS (if installed) when the RV, boat or truck is in a conﬁ ned storage area.

WARNING: If an AGS were to start and run the generator for an extended period

of time in a conﬁ ned area, a potentially fatal level of CO (Carbon Monoxide) could

accumulate.
