Off-Grid System

Off-grid means not connected to the electricity grid and therefore requires battery storage. An off-grid solar power system must be designed properly so that it will generate enough power throughout the year even during rainy season and have enough battery capacity to meet the home’s requirements.

The high cost of batteries and inverters means off-grid systems are much more expensive than grid-tie systems and so are usually only needed in more remote areas that are far from the electricity grid. However battery costs are reducing rapidly, so there is now a growing market for off-grid solar battery systems even in cities and towns.

SUNERGI is expert in designing and choosing quality products for off-grid but still very much competitive.

How it works

Solar panels capture sunlight during the day and sending generated DC electricity power to solar regulator which control the amount of charge to the battery bank.

The battery bank stores the DC electricity.

Inverter draws power from the battery bank then converts it to AC electricity to supply the switchboard.

As an option, in the event there isn’t enough power in the battery bank and the charging from solar panels is not sufficient, inverter or regulator can start a generator or allow grid to feed the power to the switchboard, with any further excess charging the battery bank.

Using quality components makes a big difference

There are so many different products available in the market, how do you know what is good, bad, or best suited to your particular situation? 

Even not all ‘Tier-1’ solar panels are equal; major differences in quality can be found even among ‘Tier-1’ panels.

SUNERGI continually research the solar technology market and understand the differences and importance of various specifications that affect how your system will perform and last.
