With a Hybrid Inverter system, you can apply different methods to generate and to consume power, whether or not automated. Latest models of hybrid inverters do have different types of incoming or outgoing power.

Basically, you may consume your power directly from your power source (PV, Wind or Generator) and your leftover power might be stored in your battery pack. From this pack, you can consume power in case there is no power production.

It is possible to keep connected with the Utility grid. In case your battery pack is running out and you have more consecutive days of bad weather than expected, the Hybrid system can obtain power from the Grid. You can also connect a Generator to produce power.

INVERTER SYSTEM

Basically, there are three methods to connect your PV-installation, via an inverter-based system, to your home electricity network:

  1. Connecting your PV-installation, via an inverter,directly to the utility, is named On-Grid. You receive your AC power from the utility and you send your AC power, via your breaker panel, to the utility company. The power is in many cases, 230 Volt.
  2. Connecting your PV-installation on a power source, such as a battery pack, is named Off-Grid. Your DC power is coming from your PV-installation, via a DC charge controller, the power flows into the DC battery pack. The power of the DC battery pack is then via a DC/AC inverter, switched to AC-power. Via your cabling network, the power will be delivered to your breaker panel. In many cases the power is 115 or 230 Volt.

ON GRID SYSTEM

Invert Power

In an On-Grid system, you are directly connected with the Utility. To make such an connection, your equipment needs to comply with several regulations. The inverter, may be an string version or a micro version. Any inverter connected to the Utility must have UL1741 certification.

Also, your electrical infrastructure (cable, wire, breakers etc.)  should comply to the NEC regulations, which means that there is at least an AC disconnect in your network. In case you are not familiar with electricity, we recommend to hire an electrician or one of our employees.

In an Off-Grid system, you are directly connected with your battery system. To make such an connection, your equipment have to comply with several regulations. To charge your batteries with PV, you need a charge controller. To convert DC into AC you need an inverter. In case you have an entire battery pack, it makes sense you go for a charge controller and inverter of the same brand, so you are able to monitor your system.

Also, don't underestimate your electrical infrastructure (cable, wire, breakers etc.) which should still comply to the NEC regulations. Even in off-grid systems, there should be a DC and an AC disconnect in your network.

Right now, we're working on a hybrid system on our premises. As soon this inverter system is finished, we'll publish you our latest experiences and pictures of course.
