APPLICATIONS Recreational vehicle electrical systems Marine house-power systems Work vehicles and specialty mobile equipment Generator-supported battery systems Shore-power installations Off-grid homes and cabins Backup power systems Solar and alternative-energy installations Energy storage systems Systems supporting computers and other sensitive electronics IDEAL FOR Buyers needing a combined inverter, charger, and transfer switch 12V battery banks requiring high charging current Systems with limited shore-power or generator capacity Applications with short-duration high-starting-power loads Installations that require selected loads to shut down during battery operation Expandable systems requiring parallel, split-phase, or three-phase capability Owners who want optional remote monitoring and system configuration PROTECTION FEATURES Output short-circuit protection Inverter overload protection High battery-voltage protection Low battery-voltage protection High-temperature protection Protection against 120 VAC being present on the inverter output Excessive input-voltage-ripple protection Bulk-charge time protection Alarm and shutdown indications for overload, low battery, high temperature, and excessive DC ripple SYSTEM COMPATIBILITY Designed for nominal 12V battery banks Supports lead-acid charging with adaptive bulk, absorption, float, and storage stages Compatible with Victron Lithium Battery Smart systems when used with a VE.Bus BMS V2 or Lynx Smart BMS Other lithium batteries require verified battery and BMS compatibility and appropriate charger configuration Compatible with solar charge controllers and grid-tie inverters in supported system designs Up to six identical units may be connected in parallel Two identical units may be configured for 120/240V split-phase output Three identical units may be configured for three-phase output Compatible monitoring and control options include Cerbo GX, Ekrano GX, Digital Multi Control, VE.Bus Smart Dongle, MK3-USB, VictronConnect, VEConfigure, and VRM Optional 100 A external current sensor can support grid-parallel PowerControl and PowerAssist applications CHECK BEFORE ORDERING Confirm that the 60 Hz-only PMP122405100 version is required. The similar PMP122405110 version supports 50/60 Hz operation. Confirm the system uses a nominal 12V battery bank. Confirm the required AC output is 120V at 60 Hz. Verify that 3.4 kW continuous output is sufficient for the combined running loads. Check motor, compressor, pump, and air-conditioning startup requirements against the 6 kW peak rating. The manual recommends a 400-1200 Ah battery bank for this model. Recommended DC fuse rating is 600 A. Recommended battery cabling is two 2/0 AWG conductors per positive and negative connection for runs up to 5 m. Recommended battery cabling is two 4/0 AWG conductors per positive and negative connection for runs from 5-10 m. AC input and main-output circuits are rated for 50 A and require appropriately sized overcurrent protection. The auxiliary output is limited to 32 A and turns off during inverter-only operation. Install in a dry, well-ventilated location with adequate cooling clearance. Parallel and multi-phase systems require identical units, equal-length DC cables, VE.Bus cabling, and system configuration. An MK3-USB interface and RJ45 UTP cable are required for direct computer configuration. Confirm battery chemistry, charging voltages, BMS requirements, and temperature-sensor requirements before installation. Normalized SKU: PMP122405100
