OFF-Grid Solar Rooftop System


Off-Grid systems allow you to store your solar power in batteries for use when the power grid goes down or if you are not on the grid.


SISRenewable Off-Grid Solar System converts sunlight into electricity without connecting to local utility grids and provide your home or building with AC power for efficient lighting, refrigeration and appliances.

The beauty of an Off-Grid solar system from SISRenewable is that it provides the most reliable power, making you independent power cuts, No more rising electricity bill.

In Off-Grid solar system, the solar panels provide the energy, which is fed into the solar controller. The solar controller charges the batteries. The AC inverter takes its power directly from the battery provides the high-voltage AC power supply.Off-Grid solutions are usually used in placed with high load shedding.Other than the regular solar PV system elements it uses batteries which increases the costs of an off-grid system.

Off-Grid Rooftop solar system

Solar Solutions Off-Grid Energy Systems(like the above example) provide your home or building with AC power for efficient lighting, refrigeration and appliances.
Special batteries are used to store energy- providing you with reliable standby power and critical load support. A back-up generator can also be integrated into your Solar Solutions Off-Grid Energy System as an emergency back-up.

Benefits of Off- Grid solar system: Provides power for your critical loads when the power grid is down.

Downside of Off- Grid solar system: Cannot be expected to provide power for all your loads since the cost and volume of batteries would be prohibitive. Off-Grid systems require a lot more specialized equipment to function that is more costly and more complex to install. Specifically they require a central/string inverter, a charge controller as well as batteries.

Summary of Off-Grid solar system: Sizing the solar array and the batteries required is complex. Detailed analysis of your requirements will be needed to provide for your minimal critical needs. You’ll also need to rewire you main electrical panel to isolate the “critical loads” so that only they are provided power in an outage. This means that your well pump, refrigerator and a few lights are provided power while your air conditioners and TV and other non-essential loads are not.
