Basic System Architecture

SAIL SOLAR 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. 

SAIL SOLAR HV Battery

HV Battery

 

50kW / 50kWh(1c)The system is equipped with a 50kWh lithium battery energy storage unit, matching 50kW power rating at 1C rate. The battery system delivers stable energy output and high charge/discharge efficiency to support demanding load conditions, capable of full 50kW continuous power output from the battery pack.

50kW / 100kWh(1c)The system is equipped with a 100kWh lithium battery energy storage unit, paired with 50kW inverter at 0.5C rate. The battery system provides stable energy output and high charge/discharge efficiency to support demanding load conditions, featuring longer energy duration for extended backup or self-consumption scenarios.

 

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.

SAIL SOLAR 50kw Inverter

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.

System Mode

  • #
    Mode I: Basic
    This is the standard basic configuration of the hybrid inverter. Solar PV modules and batteries supply DC power to the inverter. It connects to the utility grid, dedicated backup loads and regular on-grid home loads. The CT sensor monitors grid power flow. When grid fails, the system can automatically power the backup loads to guarantee essential electricity supply.
  • #
    Mode II: With Generator
    This configuration adds a generator as an auxiliary AC power source, based on the basic mode. The generator can charge batteries or supply loads when solar generation is insufficient and the grid is unavailable. It offers an extra power backup option for areas with poor grid stability or limited solar resources, ensuring continuous power supply for critical loads.
  • #
    Mode III: With Smart-Load
    Built on the basic system, this mode integrates smart load control. The inverter can intelligently manage high-power smart appliances according to available solar power, battery SOC and grid status. It optimizes self-consumption of PV energy, automatically switching on or off smart loads to make full use of on-site renewable power and reduce grid electricity consumption.
  • #
    Mode IV: AC Couple
    The AC-coupled solution allows the hybrid inverter to work alongside existing grid-tied PV inverters. The original on-grid solar system feeds AC power into the hybrid inverter for battery charging and load supply. This design is ideal for retrofitting old solar plants, adding energy storage and backup function without replacing the original PV panels and string inverters.
