Off-Grid Solar Backup Generator

What is off-grid solar generator system?

Off-grid solar systems, also known as stand-alone solar systems, provide grid like electricity in areas where grid power is either unavailable or directly replacing expensive or unreliable grid power. Off-grid solar systems consist of roof- or ground-mounted solar panels, a battery bank to store energy, an integrated backup diesel generator and an Inverter and/or Charger to act as an interface between the different inputs.


Diesel Generators are incorporated into standalone systems as a backup power source. They are used to provide power during times of increased demand or extended periods of poor renewable generation


In larger solar systems there is often a diesel generator integrated to assist in periods of higher than usual demand or to act as a backup for extended periods of bad weather. Other renewable sources like wind and hydro can also be integrated if the environment allows for this.

2 Wire Start and How it Works.

Your solar inverter & MPPT charger are the two components that control your battery system and the charging components.

When your solar array isn’t putting in enough energy and your battery system is getting low on power, your inverter will send a start signal to turn on your solar backup generator. Our solar backup generator has a multi-function controller designed for 2 wire start.

The generator controller is set in AUTO awaiting its commands. The inverter sends the signal to the generator & sensors this through the 2 wire start system.

The generator starts and produces the 240v to the MPPT charger, which converts it to the low voltage. Once the system is archive it floats voltage in the battery bank.

The inverter will send another signal to turn off the generator. The generator will be still set in Auto, awaiting another signal for the solar system.
