Solar-storage genset integrated unit refers to a multi-energy complementary microgrid system that integrates photovoltaic power generation (photovoltaic), energy storage system (storage), and diesel generator (genset). Its main purpose is to solve the power supply problem in remote areas, off-grid scenarios, or areas with unstable power, and to achieve stable, reliable, and efficient energy supply.
The photovoltaic-diesel-storage microgrid system is a distributed energy supply system that integrates solar photovoltaic panels, diesel generators, energy storage batteries, and other energy sources to form an independent power network. The system can automatically adjust the output of various energy sources according to actual demand to meet users’ electricity requirements.
Why Do I Need a Microgrid System?
1. There Is No Power Grid in Many Places
For example, mountainous areas, villages, islands, border outposts, oil and gas fields, field construction camps, and rural off-grid areas in developing countries such as Africa and Southeast Asia all lack stable grid access year-round.
2. Improve Energy Efficiency
Diesel power generation is expensive and polluting. Photovoltaic power generation is clean but unstable and affected by sunlight. Energy storage systems can adjust and balance.
After using the solar-storage-diesel solution, photovoltaic power generation + energy storage system ensures power supply during the day, and the diesel engine serves as a backup or supplements power when photovoltaic power generation is insufficient.
Application of HIITIO Products in the Microgrid Field: Solar-Storage Genset Integrated Unit
HIITIO’s photovoltaic, storage, and diesel integrated cabinet is based on the “ALL IN ONE” design concept. It is a commercial and industrial BESS with photovoltaic and diesel generator ports. It is suitable for various application scenarios, such as emergency power backup, peak conversion, and distributed solar energy systems.
HIITIO has a variety of power & capacity options from 50 kWh to 4 MWh, integrated with BMS and high voltage box. It is connected to PCS and MPPT. The PCS is a three-phase 400Vac/230Vac system. The MPPT is a high-voltage solar controller.
The solar-storage genset integrated unit is highly integrated with hybrid inverters, batteries, BMS, air conditioners, fire protection, diesel generator interfaces, etc. It supports seamless off-grid switching, integrates STS, and has a switching time of less than 20ms, enabling flexible configuration between photovoltaics, batteries, diesel generators, and loads.
HIITIO is characterized by flexibility and customizability, with multiple different options to meet the diverse needs of microgrid customers.
EMS acts as a central controller to coordinate and manage the operational status of diesel generators, photovoltaics, and energy storage.

Let’s Take a Closer Look at the Components of One of Our Top-Selling Models:
Hybrid AC/DC Integrated Cabinet with PV, ESS, and Genset (100KW/215KWh Air-Cooling)
1. LiFePO4 Battery and BMS
Lithium-ion battery – Lithium Iron Phosphate (LFP)
A lithium-ion battery is a type of secondary battery (rechargeable battery) that primarily relies on the movement of lithium ions between the positive and negative electrodes for energy storage and release.
We use lithium iron phosphate (LFP) batteries in our energy storage systems. Available brands include EVE and CATL, with a cycle life of 6,000 to 8,000 cycles.
LFP Battery Cell
Battery Cluster
Battery cells are assembled into an air-cooled battery module, which is housed inside a cabinet.
The BMS module ensures effective management and monitoring of each module and cell.
2. PCS
The PCS (Power Conversion System) comprises a bi-directional DC/AC converter and a control unit. The PCS controller receives backend commands to manage the charging or discharging of the battery and regulate grid power.
3. MPPT
The MPPT system is a PV controller. It tracks the maximum power of the PV all the time. It is a DC to DC system.

4. STS
The STS system is a power fast switch module. It is used for on-grid and off-grid fast switch (less than 20ms) to avoid load power down.
5. Air-Conditioner
The A/C system is an intelligent air-conditioner system. It supports both cooling and heating functions.
6. Aerosol
When the condensed aerosol fire suppression device receives the start signal, the aerosol generator in the cartridge will be activated to decompose the chemical coolant on the upper layer so that the aerosol generator and the coolant work together to suppress a fire.
7. EMS
Integrating local controllers, BMS, PCS, thermal management, fire protection, and other subsystems.
Tailoring solutions to high adaptability across user-side and source-side applications, we provide comprehensive lifecycle system solutions for you.
