Hongjiali New Energy (HG POWER) Ultimate Guide to Solar + Battery Storage + EV Charging Systems

December 3, 2025

Around the world, electrification is reshaping the energy landscape. The rapid growth of electric vehicles (EVs), soaring energy demand, and rising global carbon neutrality initiatives are driving the need for smarter, more resilient power infrastructures.

However, the traditional grid is struggling with:

Insufficient grid capacity to support fast charging
High peak electricity tariffs in Europe & APAC
Weak or unstable grids in Africa, Southeast Asia, and South America
Remote locations with no grid access
Growing demand for renewable integration

To solve these challenges, the world is shifting to integrated Solar + Energy Storage System (ESS) + EV Charging solutions — known as solar-storage-charging systems.

These systems enable:

Reliable EV fast charging even without strong grid support
Maximum self-consumption of solar PV
Reduced energy costs for commercial and industrial users
Off grid deployment where power infrastructure is limited
Faster ROI for charging station operators
Enhanced energy security for businesses

Hongjiali New Energy (HG POWER) delivers a complete portfolio of integrated energy systems tailored for diverse global markets.

Allows high-power fast charging without grid

AC Coupled Architecture

Best for:

Europe, Japan, Korea, and regions with stable grids
Industrial and commercial facilities
Large existing AC infrastructure

Advantages:

Flexible PV & ESS scaling
Lower system cost
Easy integration

Hybrid AC/DC Architecture

Best for:

Commercial fast charging hubs
Multi-energy stations
Mixed load + EV charging applications

Combines the reliability of AC with the efficiency of DC.

Hongjiali New Energy (HG POWER) Product Portfolio

Hongjiali New Energy (HG POWER) provides three major categories of advanced integrated systems:

Solar–Diesel–Storage Hybrid Systems (GCCF Series)
Solar–Storage–Charging All-in-One Systems (GCC Series)
Commercial & Industrial (C&I) Energy Storage Systems (CGS Series)

Solar–Diesel–Storage Hybrid System (GCCF261K-125 / GCCF110K-50)

Three input ports:

DC emergency charging port (vehicle must support discharge)
Diesel generator input
Solar PV input

One output port:

AC output (380V three-phase + 220V single-phase)

Key Benefits:

Hybrid power supply for construction sites, mining, remote operations
Flexible charging modes: PV, diesel, or vehicle discharge
Suitable for off-grid or weak-grid environments
Provides stable AC power for tools, machinery, lighting, and EV charging
Efficient supplement to traditional diesel generators, significantly reducing fuel cost

This all in one system is ideal for regions lacking reliable grid power.

Solar–Storage–Charging All-in-One System (GCC261K-125)

DC Bus Architecture

Inputs:

100–125 kW AC grid input
100 kW solar PV input (no PV inverter required)

Outputs:

120 kW DC fast charging gun
120 kW AC load output

Advantages:

Storage-assisted power boost
Enables high-power EV fast charging even when grid capacity is limited.
On-site solar consumption
Maximizes use of renewable energy, reducing electricity costs.
Simplified installation
No PV inverter, no transformer upgrade, minimal electrical construction.
Hybrid input modes
Grid or PV can be used independently or simultaneously.
Acts as backup power
AC load output can supply emergency or temporary electricity during outages.

Commercial & Industrial Energy Storage System (CGS261K-125)

AC Coupled Architecture

Specifications:

125 kW charge/discharge power
261 kWh storage capacity
Fully charged or discharged within 2 hours

Designed for Peak–Valley Arbitrage

Sizing Principles:

Review electricity bills to calculate peak load consumption
For “1-charge-1-discharge”, size ESS according to daily peak usage
For “2-charge-2-discharge”, size ESS based on the smaller of two peak periods
Ensure the transformer has enough valley-period capacity to charge the ESS

Limitation:

Cannot discharge during grid outages (AC systems require real-time grid reference)

This ESS solution is ideal for factories, commercial buildings, industrial parks, and any facilities seeking energy cost reduction through load shifting.
