    AC power cord. Even though it is dif- fi cult to calculate exactly how long an inverter will run a particular ap- pliance, the best advice is trial and error. Your MM Series inverter has a built-in safeguard that automatically protects your batteries from being over-discharged.

  • Page 9: Standard Features And Benefi Ts

    1.0 Introduction Standard Features and Benefi ts The MM Series inverter converts 12 Volts Direct Current (VDC) power from your battery to 120 Volts Alternating Current (VAC) power. models with the multi-stage battery charger feature, the incoming AC power is optimized using Power Factor Correction (PFC) technology to keep the inverter’s battery bank fully charged.

    However, when an external AC source is connected, another neutral-to-ground connection is introduced in the system. When the MM Series is connected to this external AC source, the internal relay automatically opens the neutral-to-ground connection. This design keeps two neutral-to-ground connections from occurring at the same time.

  • Page 28: 3.0 Operation

    3.0 Operation 3.0 Operation Operating Modes The MM Series inverter has two normal modes of operation; Invert Mode, which powers your loads using the batteries, and Transfer Mode, which powers your loads from the incoming AC power (i.e., shore pow- er or a generator).

  • Page 29: Protection Mode

    Charge Mode (not available on all models) Some MM Series models are equipped with a multi-stage battery charger feature. This includes an automatic 4-stage charging process: Bulk, Absorb, Float and Full Charge; and a manual charge stage: Equalization (the ME-RC50 is required to enable Equalization charge).
  • Page 30 BTS is below 77° F (25° C), and decrease if the temperature around the BTS is higher than 77° F (25° C). ** The MM Series uses changeable settings (see Table 5, Inverter Default Set- tings) that are adequate for most installations. However, if you determine that some of your operating parameters need to be changed, the ME-RC50 remote control can be purchased to allow changes to those settings.
