The answer is yes! For longer outages or off-grid setups, an external generator is often a great option.
- Looking for augmenting your energy independence?
- Expecting long outages this winter season?
- Do you want to feel safe when completely disconnected from the grid?
Installing an external gas-power generator could be a great choice to consider for your home. This will allow you to recharge the batteries connected to your inverter even when the solar production is at its lowest, like for example during a winter snowstorm.
The Renogy X Hybrid inverters can be hooked up to any portable or HSB generator using the L1, L2, N terminals.
- Home Standby Generators (HSB) are permanently installed, automatic, run on natural gas or propane, and are capable of powering any size home.
- Portable Generators provide electricity by running a gas-powered engine that turns an on-board alternator to generate electrical power. Power outlets on the unit allow you to plug extension cords, electric-powered tools, and appliances into it.
When you connect the generator to the Dry contacts 1A and 1B of your Renogy X Hybrid inverter, the inverter can communicate with the generator and control its operation starting and stopping it according to the mode selected on the inverter.
The generator is intended to charge the batteries and provide backup to the home (if the mode is selected). Attached is a reference guide for further details.

OFF-GRID setup
The Generator is connected to the grid port of the inverter. The connecting cables shall be installed with CTs. It is used in some off-grid situations. The system diagram is as follows.
GRID-TIED setup
The Generator is normally connected to the Generator port. The connecting cable between the Generator and the inverter does not need to be installed with CTs. The CTs should instead be installed on the connection line of the power grid. The system diagram is as follows.
