Frequently Asked Questions

The following are the most frequently asked questions about our 5KW Off grid Solar Power System in our communication with clients, and we hope that these answers will help you
1What can I run on 3.5kw off grid solar system?
Our 3.5KW off grid Solar power system is with a 3.5KW MPPT Inverter, the rated output power is 3500W, the max peak power is 7000W, the Loaded motor capacity is 2HP, So if the motor loads power are less than 2HP, It can work well. Such as A/C, washing machines, AC fans, lights, refrigerators, TVs, and more.
2How much power does a 3.5kw solar system produce?
The amount of solar power generated varies from region to region, depending on the local solar hours.

For example,
In the Philippines, the effective solar insolation time is 3.8 hours per day on average, so a 3.5KW off-grid PV system can generate 9KWH per day.
In Nigeria, the average effective solar insolation time is 4.5 hours per day, so a 3.5KW off-grid PV system can generate 10.6KWH per day.

You can use this formula to calculate the amount of electricity generated: Total solar Array power * solar hours * 0.75
3How many panels in a off grid 3.5kw solar home system
Our standard configuration is 7pcs 450W Mono Solar Panel, But It is customized, You can choose less to save cost.
4Is your 3.5KW Solar Panel System single Phase or Three Phase?
It is single phase AC110V or AC220V solar power system.
5How will you ship the solar system to me?
To avoid breakage in transit, we generally use wooden boxesWe will ship the solar system by wooden case.
