Tandem GEN 48S-4440


The Gen48S-4400 provides a huge benefit for anyone relying heavily on generator power.  It saves fuel and extends generator life by enabling part time use of the generator.  It is "solar ready" meaning that a charge controller and solar modules can be easily added when purchased, or later.

Even better, the system comes pre-wired and pretested to simplify installation.  The 48S systems are designed to be stationary systems (not mobile), and to interface with the customer’s electrical panel (1).

This application shows one of the big advantages of lithium batteries.  Instead of running your generator continuously for long periods or time, you can rapidly charge advanced lithium batteries whenever the generator is running, then turn off your generator and coast on battery power alone.  

The major components of the Gen48S-4400 are:  

  • 48 volt,
  • 4400 watt pure sine wave inverter,
  • 8500 watt charger,
  • 60A @120V pass through from the generator,
  • 4 x 110 Ah lithium batteries.
