In September 2025, we installed a residential energy storage system in Cambodia. The customer feedback that the system is working well and shared related photos.
The system is configured as follows:
1.Solar panels: 252pcs Longi 645W (LR7-72HVH-645M)
2.Hybrid Inverter: 2pcs Deye 75kW hybr...
Grid-forming technology is a power system innovation that enables distributed energy resources—such as solar photovoltaics, wind power, and energy storage systems—to autonomously and coordinately form local grids through inverters. This technology allows these resources to operate indepe...
The recent Hurricane Melissa devastated Jamaica, causing unprecedented damage. The hurricane's destructive power will significantly drive and change the region's demand for solar system, particularly PV systems combined with energy storage.
Many Jamaican customers have reported that previously...
Today, we’ll take an in-depth look at the three major US version inverter series available on the GreenSun platform: Deye,Solis, GreenSun Self-Developed Series. We’ll help you make the right choice and find the perfect "heart" for your energy system.

Grade A, B, and C cells are quality classifications for lithium battery cells, indicating the quality control standards and performance levels attained during production.
Grade A cells are those that fully meet technical parameter requirements without any anomalies during production. These ce...
A BMS typically adopts a three-level architecture (slave control, master control, and master control) to achieve hierarchical management and control from battery modules to clusters to stacks. The following briefly describes the three-level architecture of a BMS system.
Level 1: The Battery M...
In our connected world, power is as vital as air. A sudden outage can mean lost data, halted production, or crashed servers. That's where the unsung hero—the UPS—steps in.
How UPS Keeps You Running？
A UPS stands guard between your equipment and the grid. It stabilizes power while chargi...
Communication between the Energy Storage BMS and the EMS
The display screen of the master controller unit (BMS) displays information about the entire PCS battery stack and transmits this information to the monitoring system (EMS) via Ethernet (RJ45). This information includes battery cell, batt...
Battery Management System (BMS) is an electronic system that monitors and manages rechargeable battery packs, especially lithium-ion batteries.
In an energy storage system, the BMS, often referred to as the "intelligent hub," performs essential functions such as battery monitoring, protection, bala...
1. External Inverter
Greensun's outdoor all in one cabinets generally use 50-125kw hybrid solar inverters (such as Deye, Solis, Growatt, Greensun, etc.), which can switch from on-grid to off-grid operation. This inverter has Wi-Fi remote monitoring, IP65 protection, and 5 years w...
The integrated model deeply integrates the three core functional units, MPPT, PCS, and ATS, at the control and circuit levels. Its core advantages lie in efficiency, convenience, intelligence, and cost-effectiveness (in terms of initial total investment). However, it suffers from poor flexibility, l...
