What is an off-grid solar power system?
Off-grid solar power system is a system that uses solar energy (green and clean energy) to provide stable power to AC devices when there is no grid or grid is only used as a backup.
Building an off-grid solar power system is a difficult task that many people want to but don't know how to start. It is common for us to design and build a complete off-grid solar power system in areas where there is a shortage of electricity or for the concept of environmentally friendly, but how to build it reasonably? This article will use the simplest language to help you answer various doubts about building off-grid solar power system. Rico Chen, founder of CNBOU, engaged in the off-grid solar power business for ten years, we have collected a lot of information in the sales of about 15000 inverters each year, and finally presented a set of relatively reasonable off-grid solar power system solutions.
It depends on whether your system is running at a full load for a long time or using it occasionally, just like: induction cooker or kettle, etc. Because if we only use several minutes or less than half an hour, we don't need to match with solar panel with same power. Solar panel with 900W can generate electricity 4.5kWh in 5 hours, the electricity consumption of 2kW pure sine wave inverter in an hour is 2kWh, if just use occasionally, it will be enough. Of course, you may say I have many LED lights used in the off-grid solar power system of the farm, that you may need configurative 6*300W Mono/polycrystalline solar panel. Meanwhile, you need to replace the Mppt solar charge controller that is twice as large. Here we highly recommend Mppt solar charge controller. Although PWM is cheap, its efficiency is 20%-30% less than that of Mppt, which will lead a waste of your solar panel.
It depends on how long you require your system to run on batteries without any assistance? There are many types of 5KW off grid solar inverters on the market, what we see are usually two types:
1. Solar panel input is less than 5000W
2. Solar panel input is greater than 5000W.
When you need to install off-grid solar system on your boat dock, I think it is a professional work. Boat dock is usually built without grid, if we need to apply for a transformer to power a separate boat dock, it will be very expensive to achieve. Therefore, choosing an off-grid solar system for free, eliminating the need to build a transformer to provide grid (about $20,000) and not having to pay for the usual grid, is a good solution for your boat dock.
Off-grid solar system on boat dock from a solar energy system can power the following:
●Washing machine, microwave oven
●Charge to Mobile phone, laptops, tablets
●Party accessories like speakers, TVs
Many owners of boat docks wonder if off-grid solar system will cover all their use cases or not. The answer is yes. This off-grid solar system can work all year round.
We will end here with 300W-5000W small off-grid solar power system, these come for a large number of actual customer cases we have collected and then recommend. If you want to know more about the information, please contact us. Also if you have batter suggestion, please let us know, and let's contribute to the development of off-grid solar power system.
