Kit Solar Off Grid System is composed of solar panels, Solar Off-grid Inverter, MPPT charge controller and battery pack.

Solar off-grid inverter is the core device of solar power system, it converts DC power produced by solar panels to AC power to provide electric energy for appliances. MPPT charge controller charges the solar electricity into batteries. When solar energy is not enough for the loads, or at night, the battery pack will discharge to replenish energy for loads.

How to determine the size of an off-grid solar system
When installing an off-grid solar system, determining the size of the system you need is an early and absolutely critical step.

It affects the type of equipment you need, how much work the installation will involve, and of course the total cost of the project. The size of the solar installation depends on the amount of electricity the system needs to provide.

There are two different ways to calculate the quantity you need, based on:

Your current usage
Load evaluation
Determine the size of the solar setting according to the usage
You can use this option if your goal is to maintain your current lifestyle when switching from on-grid solar to off-grid solar. To do this, you only need to refer to your monthly electricity bill to determine your electricity consumption (in kilowatt hours).

You can then adjust the size of the off-grid system of that size, although you want it to be a bit larger—say 10% more—to allow for solar inefficiency.

Solar installation size based on load evaluation
The second option is to perform a complete load evaluation to determine how much power you need.

1. Calculate total electricity demand
Start by listing all the devices you plan to use and the number of hours you will use each device. This allows you to calculate the power consumption of each device, as well as the total power consumption in a day.

Knowing how many kilowatt-hours will be used in a day, you can determine the size of the solar panel array and solar cell storage.

2. Calculate instantaneous load requirements
You must also calculate the number of devices that may be running at the same time. This will help you calculate the instantaneous power requirements. You need to understand these requirements to properly adjust the size of the inverter (the inverter runs on AC loads).

3. Determine the battery storage capacity
Next, you need to decide how much energy storage you want. Do you want to cover a day's usage, or do you want additional backup capacity?

When it comes to solar battery backup, the rule is usually that you need enough storage space to cover at least 2-3 days of the highest usage time of the year.

4. Design a system around your number from steps 1-3
Figure out the dimensions of these three key components (solar panels, inverters, and battery storage) are usually large enough, and solar equipment suppliers can customize a complete off-grid kit for you.
