What is Off Grid Solar System?

An off-grid solar system pulls energy from the sun and its rays through solar panels, which most often are mounted to the roof of a home, cabin or RV. The energy the panels collect is then routed to a battery that stores the energy until you need it, when an inverter converts it into electricity.            An alternative to off-grid solar systems is a hybrid system, which remains tied to the grid but includes a solar battery bank to store excess energy.

Frequently Asked Questions

We have compiled the most frequently asked questions about our off grid solar system here for your convenience, but please feel free to contact us if you have any additional questions.

The daily energy output of a solar power system depends on a number of factors,including  the total power of the solar panels used, the local hours of sunlight, as well as the temperature and weather conditions. Generally speaking, a 5 kW solar power system can generate approximately 5 kWh of electricity per day, given 5 hours of sunlight at a solar irradiance of 1000 W/m².

Lead-acid batteries have a lifespan of about 800 cycles, while lithium batteries have a lifespan of about 5000 cycles. If the budget is limited, it is recommended to use lead-acid batteries, and if the budget is sufficient, it is recommended to purchase lithium batteries.

Single Phase vs 3-Phase Solar Inverter
A single-phase solar inverter has one live wire which connects to your home. While a 3-phase solar inverter has 3 live wires connected to your home.

A 3-phase solar inverter sends the electricity evenly across the 3 wires which minimises the voltage drop problem associated with a single phase power supply. It needs to be noted that a 3-phase solar inverter will probably cost more than a single-phase inverter.So should you buy a single phase or 3-phase solar inverter?
A single-phase inverter usually comes in a capacity of less than 5kW. But if you are looking for an inverter larger than 5kW, and you have 3-phase power in your home then a 3-phase solar inverter is ideal. If you have a single-phase power supply, you only need a single phase inverter.

For a 3-phase supply, the best solution is to go for a 3-phase inverter. However, if your solar power system is less than 5kW, go for a single-phase inverter.

Benefits of 3-Phase Solar Inverter
The 3 phase inverters come in a capacity of more than 5kW, up to 30kW which allows users to install a high capacity solar system.
3-phase solar inverters manage voltage rise and reduce the chance of appliance failures due to high voltages as the voltage rise in a single-phase connection is higher than that of 3-phase power. By using a 3-phase connection, the power supplied to the grid is distributed evenly and leads to grid stability.
It increases the local grid voltage and your circuits will have less chance of short-circuiting due to high voltage issues.
If a 3-phase inverter is chosen, the consumers can meet their energy demands easily reducing their dependence on the grid for energy and leading to reduced utility bills.

A photovoltaic system consists of many components, each with different warranty periods. The photovoltaic module has a power warranty of 25 years and a material warranty of 12 years. Grid-connected/hybrid inverters have a 5-year warranty, while off-grid inverters have a 2-year warranty. Lead-acid batteries have a 3-year warranty, while lithium batteries have a 10-year warranty. Photovoltaic cables have a 5-year warranty.The combiner box has a 2-year warranty.
