MM Series Modified Sine Wave Inverter/Charger


Extended Product Protection with PLUS Plan!

Model # 8632804 | Mfg # MM1212-U
In stock online.

A new generation inverter designed to accommodate entertainment systems and small appliances in smaller RVs, boats and cabins in an all new design. Based on the popular ME and MS Series inverters, the MM is smaller, lighter and less expensive while retaining all the built-in protection and reliability of ME and MS models. The MM uses a PFC (Power Factor Corrected) charger, which is 85% efficient and the same charger topology used in all Magnum models.

The modern, hourglass case, paired with the die-cast aluminum base combines form with function, creating an attractive unit that uses its base as a heat sink for superior high temperature operation. The MM Inverter/Charger is fan cooled, enabling the unit to work well in confined spaces. If the inverter does exceed its temperature limits, it will automatically shut down, then restart when it cools down. The standard 7 or 16 amp transfer relay will pass AC power through the inverter when using shore or generator power.

Comments about Magnum Energy MM Series Modified Sine Wave Inverter/Charger:

First one dead out of the box, second lasted 2 weeks but failed on power interruption at marina, FET board blew on 3rd unit after 6 months and now 1 year later unserviceable again, off warranty so will replace with something hopefully that will work.

Service and delivery comments:

While the unit has failed 4 times the service from Magnum was very good and they stand behind their warranty.
