They are a combination of the two types above. Batteries allow power to be stored in battery cells without converting it into DC like a DC coupled storage, yet they can also provide protection against grid outages. They have the highest costs in market. Hybrid inverters are programmable. But one key advantage is the smaller efficiency drop over time compared to the alternatives.

The inverter is the heart of your solar power system. The inverter’s primary functions are to convert the DC power from the panels into AC power for your home and to select the most productive operating voltage for the panels. Inverters come in a wide variety of types and sizes, suited to different systems.

Inverters for Solar Power

A solar energy system is incomplete without a solar inverter. Despite their simple function as DC to AC power inverters, they are far more than that. In addition to being the heart of your solar power system, solar inverters are also its brain

Types of Solar Inverters

The most common types of inverters are string inverters, which are mounted on your wall and connected to all your solar panels. This category includes most of the inverters we sell.

How Solar Batteries Work?

Batteries store excess solar energy from the PV system for use at night. Another salient feature of storage systems is that it protects your house from load sheading and helps reduce dependence on grid supply.

• Solar Panels convert sun light to DC electricity
• The inverter converts this to AC, which gets used by home appliances during the day time
• The surplus power generated by the panels, which otherwise gets fed to the grid, is used to charge the batteries
• Once the batteries are full charged, the remaining solar energy is exported to the grid as usual
• The stored energy in the battery gets utilised during the night time and thus ensuring minimal dependence on the grid
