Offering independence from the grid, these systems empower homeowners and businesses with sustainable, cost-effective power solutions. Dive into the realm of non-grid tied solar systems to uncover their benefits, components, and the path to energy autonomy.

Non-Grid Tied Solar Systems Overview

Non grid tied solar systems

Non-grid tied solar systems are independent power systems that generate electricity from sunlight without being connected to the electrical grid. They are often used in remote areas or as backup power sources.Non-grid tied solar systems typically consist of solar panels, a charge controller, batteries, and an inverter.

The solar panels convert sunlight into electricity, which is then stored in the batteries. The inverter converts the DC electricity from the batteries into AC electricity, which can be used to power appliances and devices.

The primary components of a non-grid tied solar system include solar panels, charge controller, batteries, inverter, and optional components such as mounting structures and monitoring systems. Each component plays a specific role in converting sunlight into usable electricity and storing it for later use.

Solar Panels

Solar panels are the fundamental component of any solar system. They consist of photovoltaic (PV) cells that convert sunlight directly into electricity through the photovoltaic effect. The output of a solar panel is measured in watts (W) or kilowatts (kW) and is determined by factors such as the number of PV cells, their efficiency, and the amount of sunlight available.

Charge Controller

A charge controller is a critical component that regulates the flow of electricity between the solar panels and batteries. Its primary function is to prevent overcharging of the batteries by limiting the charging current and voltage. Charge controllers also protect the batteries from damage caused by over-discharging or deep discharging.


Batteries are the heart of a non-grid tied solar system, as they store the electricity generated by the solar panels. The capacity of a battery is measured in amp-hours (Ah) or kilowatt-hours (kWh) and represents the amount of electricity it can store.

Batteries come in various types, including lead-acid, lithium-ion, and flow batteries, each with its own advantages and disadvantages.


An inverter is responsible for converting the direct current (DC) electricity generated by the solar panels and stored in the batteries into alternating current (AC) electricity. AC electricity is the standard form of electricity used in most homes and appliances.

The output of an inverter is measured in watts (W) or kilowatts (kW) and should be sized appropriately to meet the electrical load requirements of the system.
