They cannot work together.
Unlike the electric grid, your generator cannot absorb as well as generate power. So, excess power created by your solar-powered inverter would burn out your generator when they together create more power than what is used by your house. To prevent that, your grid-tied inverter was designed to shut off the solar power when the grid goes down.
Your only alternative is to add a battery-based system and not use the generator when you have the solar system and batteries producing enough power. However, that is usually much more expensive than a generator.
You should not use the generator when solar power is available.
Assuming that you are using an AC generator, you can add a grid-connected inverter that will synchronize with the AC generator output, so both will work together but solar power will be lost if the generator is providing enough power. Just connect both the generator and inverter output together.
DC power is much more efficient. So, if you are using DC equipment, you just connect the generator output and DC solar output together if they are the same voltage range. A DC generator will charge the battery, which also charges from the solar panels, and everything works from the same battery.
You should check with your installer first what kind of inverter is being used, and what type of system you have. Hybrid solar systems can work with generators, but making an on-grid solar power system may require some extra hardware. PV plus Genset hybrid systems are somewhat complicated, as the solar inverter should be able to sync with your Genset's frequency.
It is always best to check with your installer. If they cannot help, then at least ask them what model and what type of solar inverter you have.
In some cases, you can find this possible depending on the technology used.
The generator will produce an analog of sine power, while solar produces DC and needs to convert to AC. If you want to use them together on one circuit, they need to be matched, in sync, and phase. It would be better to have the two sources as supplies to separate loads.
Here are some steps to consider when integrating a generator with your solar energy system:
Step 1: Choose a compatible generator
The first step is to choose a generator that is compatible with your solar energy system. Look for a generator with a pure sine wave output, which is essential for powering sensitive electronic devices without causing any damage. Also, ensure that the generator's capacity is sufficient to power your home or business's energy needs.
Step 2: Install a transfer switch
To integrate a generator with your solar energy system, you need to install a transfer switch. A transfer switch ensures that your solar energy system is disconnected from the grid during power outages and that your generator is connected to power your home or business. A transfer switch also prevents power from the generator from flowing back into the grid, which can be dangerous for utility workers.
Step 3: Seek professional installation
Integrating a generator with your solar energy system requires professional installation to ensure that it is done correctly and safely. At Enlightened Solar, we offer generator installation services to our customers to ensure a seamless integration.
