Microtek 3.5 KW off-grid solar system power solution design

As the world becomes more conscious of climate change, many people are looking for ways to reduce their carbon footprint and minimize their reliance on traditional energy sources. One way to achieve this is by installing an off-grid solar system to power their homes.

What is a 3.5 KW off-grid solar system?

A 3.5 KW off-grid solar system is a self-sufficient system that generates electricity from solar panels and stores it in batteries. This system is designed to power homes and businesses that are not connected to the grid or lack access to electricity, and therefore rely on alternative energy sources to meet their electricity needs.

3.5KW off-grid solar system design household load instructions

We can find the appropriate installation capacity for a household through calculations:

Assuming a household requires an average of 12 KWh of electricity per day. If the average daily sunlight in the area is 4 hours, then we can calculate the required power as 12(KW/h) / 4h = 3KW.

1. Solar panels 250W*12

Solar panels are the primary component of any solar system. They are designed to capture sunlight and convert it into electricity through the photovoltaic effect. 

For a 3.5 KW off-grid solar system, you will need about 250w*12 solar panels to provide 3kw of electricity, it’s depending on their wattage and efficiency.

2. Off-grid inverter - we recommend Sunshine 3.5 KW off-grid solar inverter

The 3.5 kw solar inverter converts the DC (direct current) electricity stored in the batteries into AC (alternating current) electricity that can be used to power appliances and devices. A good inverter for a 3.5 KW off-grid solar system should have a capacity of at least 4 KW.

3. Batteries:

Batteries are used to store the electricity generated by solar panels. The batteries are usually connected in series to increase the voltage and capacity of the system. For a 3.5 KW off-grid solar system, you will need at least 4 deep-cycle batteries with a total capacity of about 400 Ah.
