Case Study
Off-grid system
As a decentralized, flexible, and affordable energy supply, a PV-powered off-grid system is a perfect solution for remote areas without grid coverage. Featuring high efficiency and flexibility, Uchoicenergy PV off-grid systems can meet various power demands from 2kW to 135kW, effective in combating climate change and helping developing countries to reduce fuel dependence. There are three different ways for configuring an off-grid system, DC-Coupled PV, AC-Coupled PV, and a combination of both. Each has its unique advantages regarding system efficiency, battery life expectancy, and flexibility.
（2kW-135kW）
AC+DC Coupled PV System: Ideal for scenarios with high daytime power consumption and requiring backup energy at night. It uses solar energy directly to power loads at a higher efficiency to secure the daytime high consumption and stores the surplus in batteries to guarantee uninterruptible power at night. Apollo Matrix can regulate the PV inverter’s output power to prevent batteries from overcharging.
