I Only Have 88 Volts Coming Out of My RV's Power Inverter
by Gene c. Staley
(Winston Salem, NC)
With two fully charged marine batteries wired in parallel I am only getting 88 volts through my inverter. It is a 500 watt msw inverter and I am in the process of installing a 2500 watt one. Any idea why the voltage is so low coming out of the inverter?Protect your RV and your family while on the road: Join Good Sam RV Emergency Road Service Today and save!
ANSWER: Greetings Gene thanks for submitting your question on our Ask An RV Question Page.
I am going to assume that the 88 Volt reading you are getting from the outlet on the inverter is accurate. I am also going to assume that based on your statement that the batteries are fully charged that you have also load tested the batteries to make sure that the battery voltage is not dropping because the batteries are weak and not properly handling the load of the inverter.
I am also going to assume that the inverter is properly and securely connected to your house batteries and not a cigarette lighter receptacle and that all connections are free of corrosion. I am also going to assume that your inverter and house batteries are properly grounded.

If all of my assumptions are correct then the problem is in the Inverter itself and it needs to be replaced.
I hope this helped.
