Parallel Generator Kit Compatibility With Solar Systems — Is It Possible?

Compatibility Considerations

When integrating a parallel generator kit with a solar system, it’s essential to consider the compatibility of the inverter, charge controller, and generator control panel. Most modern solar inverters have a built-in generator transfer switch (GTS) or can be connected to a GTS unit, which automates the switch between solar and generator power. A compatible GTS unit can be programmed to switch to the generator when the solar array is not producing enough power.

Selection of Generator and Inverter

To ensure compatibility, select a generator that matches the solar panel array’s inverter wattage rating. Typically, you’ll need a generator with a wattage rating that’s 10-20% higher than the inverter’s maximum capacity. For example, if your inverter has a 5 kW rating, a 5.5-6 kW generator would be suitable. It’s also crucial to consider the generator’s voltage and frequency stability to prevent damage to the inverter and solar equipment.

Parallel Generator Kit Installation

When installing a parallel generator kit, follow the manufacturer’s instructions and guidelines for a safe and efficient setup. Typically, the kit will include a controller, wiring harness, and connectors. Ensure proper grounding and bonding to prevent electrical shock and equipment damage. After installation, test the system to guarantee a seamless transfer between solar and generator power.
