High Quality 50KW 50kwh/100kwh Hybrid Solar System for Energy Storage System Project
SAIL SOLAR 50kW hybrid solar energy storage system is suitable for small and medium factories, farms, shops and large estates. It supports grid-tied, off-grid and UPS backup modes. Solar power supplies loads with priority during daytime, and surplus energy is stored in batteries. It can switch to off-grid power supply seamlessly during grid failure to keep critical equipment running.
The system be equipped with LiFePO4 batteries, and battery capacity is expandable. It comes with an intelligent monitoring platform to remotely check power generation, battery SOC and load status. Complete protections against overvoltage, overcurrent and overheating are built in. With CE certification, it is ideal for commercial & industrial projects in unstable grid areas.

Basic System Architecture

This diagram illustrates the typical system configuration of the hybrid solar energy storage system. PV modules and batteries supply DC power to the hybrid inverter. The inverter connects to the utility grid, backup loads, smart loads and regular on-grid household loads. A generator can also be integrated as an auxiliary AC source for off-grid operation.
It supports remote monitoring via Wi‑Fi, LAN or 4G/GPRS through cloud services, accessible on computers and mobile phones. A CT sensor is fitted for grid power measurement. The system can power various household and office equipment including motor loads such as refrigerators and air conditioners.

An integrated BMS continuously monitors voltage, temperature, and state of charge, ensuring safe operation and long service life. The modular and scalable design allows easy system expansion and seamless compatibility with hybrid inverters.

Inverter
The Deye 50kW hybrid inverter is designed for commercial, industrial, and high-energy-consuming residential solar storage systems requiring high power output and reliable energy management. It integrates solar photovoltaic, lithium-ion battery storage, and grid interconnection into a single intelligent platform, supporting both grid-connected and off-grid operation.
With its powerful power conversion capabilities, this inverter ensures stable operation under high loads and complex grid environments. Seamless switching between grid-connected and off-grid modes provides uninterrupted power to critical loads during grid outages.

FAQ
Q: What is the difference between the 50kW/50kWh (1C) and 50kW/100kWh (0.5C) versions?
A: The 50kW/50kWh 1C system can deliver full 50kW power for 1 hour, suitable for short high-power backup. The 50kW/100kWh 0.5C system supplies 50kW for 2 hours, ideal for longer-duration power backup and higher PV self-consumption.
Q: Can the system automatically switch to backup power when grid fails?
A: Yes. It offers seamless transfer to backup loads once grid power is lost. You can also connect a generator as a supplementary AC source for extended off-grid operation.
Q: What are the available system configurations for this 50kW hybrid energy storage system?
A: There are four working modes: Basic mode, mode with generator, mode with smart load and AC-couple mode. It supports new PV installation as well as retrofitting existing grid-tied solar systems.
