Principle of Solar Energy

The Off-Grid solar system is an electricity generating solar PV power system that is not connected to the utility(State) grid, and has to be connected with batteries for electricity storage.

It consists of solar panels, Charge Controller (regulator), Battery, off grid Inverters, Mounting Brackets and solar system connection equipments such as MC4, PV Cable and Installation Tool Box.

Users can store the excess power in the batteries for usage at night or backup of sudden power cut. The inverter converts the DC power into AC for loads single phase (110/120V; 220/230/240Vac) or three phase (240V; 380V; 480Vac) etc. It is also called Stand Alone System (SAPS) functioned as UPS.

Frequently Asked Questions

1. What is an Off-Grid Solar System?
It is a standalone PV power system not connected to the utility grid. It uses batteries to store electricity generated by solar panels for use during the night or power outages.
2. Can this 15KW system run industrial equipment?
Yes, this system is designed for home, commercial, and industrial applications, providing up to 15000W of load power.
3. What types of batteries can I use with this system?
The system is compatible with Deep Cycle GEL, AGM, and Lithium/LiFePo4 batteries depending on your storage requirements.
4. What is the lifespan of the solar panels?
The high-efficiency mono-crystalline solar panels included in this configuration come with a 25-year warranty.
5. Does the system support both 110V and 220V outputs?
Yes, the inverter can be configured for EU standards (230/380V) or US standards (120/240V) for both single and three-phase requirements.
6. Is the mounting bracket suitable for all roof types?
The brackets are made of Aluminum Alloy or Galvanized steel and can be customized for installation on flat roofs, pitched roofs, or ground surfaces.
