"I wanted to let you know I am very pleased with the service you gave & the quality & condition of the solar panels I received from EcoDirect. I will purchase more items in the future from EcoDirect and will be sure to tell others about your fine operation."

"Thanks EcoDirect! My solar system is up and running; waiting for City and San Diego Gas & Electric inspections this week; so far so good!"

"I enjoyed ordering what I needed. It was simple and fast, no issues what so ever. If I need something else and its at a good price, I will defiantly order from here again. Also the shipping is at a good price."

- Simon
My shipment arrived on time, as predicted. Very, very good performance by EcoDirect. What more could you ask for from an online material supplier? Looks like the quantity from Quick Mount is spot on & the rails were bundled safely. EcoDirect will be my recommended source to my friends & neighbors for solar.

Description Datasheet

Magnum Energy 900 Watt 12 Volt Off-Grid Inverter

Pure Sine Wave
Manufacturer Part Number: MMS912E

The MMS-E Series Inverter/Charger is a pure sine wave inverter providing a cost effective solution for those with smaller power needs. Versatile, easy-to-use, and lightweight, the MMS-E Series provides a reliable base for your energy system.


  • Standard transfer relay: The standard 20 amp transfer relay will pass AC power through the inverter when using shore or generator power.
  • Low/high battery protection: If your battery voltage reaches below 10 VDC or above 17 VDC, the MMS-E Series will automatically shut down.
  • Versatile mounting: Mount the MMS-E Series on a shelf, bulkhead, or even upside down.
  • Fan cooled: The MMS-E Series 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 and then restart when it cools down.
  • Current overload protection: The MMS-E Series will automatically shut down if its output wattage is exceeded or it detects a short in the wiring, saving the unit from costly damage.
  • Convenient switches: The MMS-E Series comes with an on/off front-mounted switch with an easy-to-read LED indicator.
  • Circuit breaker protection: This model comes with built in input and output circuit breakers for ease of installation.
  • Battery temp sensor: The standard battery temp sensor monitors temperatures from 0 - 50° C.
  • Buy with ease: The MMS-E Series is backed by a two-year (24-month) parts and labor warranty.

Detailed Description

Introducing the MMS-Export Series Inverter/Charger - designed specifically for countries with 230Vac/50Hz power for installations that only need to run smaller loads and appliances and require a pure sinewave inverter output .

The MMS-E models are smaller, lighter and less expensive while retaining all the built-in protection and reliability of the MS models. The battery charger uses a PFC (Power Factor Corrected) charging topology, which is 85% efficient and the same charger topology used in all Magnum inverter/charger models.

The MMS-E Series inverter/chargers are powerful, easy-to-use, and best of all, cost effective. The MMS912E is currently available.

Power Factor Corrected (PFC) Charger:

The PFC charger is built into all of Magnum's inverter/chargers. It uses less energy from a generator than a standard charger – using 25-30% less AC current than standard chargers.

Attractive styling:

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.

Safe and Reliable:

The MMS-E Series is listed to the stringent CE requirements, ensuring the inverter/charger is safe and reliable.
