100kW 225kWh Battery Storage Solution in Heibei China
HBOWA supplied a 100kW 225kWh off-grid solar battery storage system for a mountain resort hotel in Hebei, China. The hotel is located in a mountain area where connection to the national grid is difficult, so the customer needed an independent power supply system for daily hotel operation.
The project combines solar PV generation, 225kWh battery storage, and a 100kW Solis three-phase high-voltage hybrid inverter to provide stable self-use electricity for the resort.

Customer Challenge
The resort hotel is located in a mountain area, making grid connection difficult and expensive. The customer needed an independent power system that could support daily hotel operation without relying on the grid.
Because hotel loads continue during both daytime and evening hours, solar power alone was not enough. The customer needed battery storage to store daytime solar energy and supply electricity when solar generation was unavailable at night or on rainy and snowy days.
Energy Storage Solution
HBOWA provided a complete 100kW 225kWh off-grid solar battery storage solution.
The system includes:
- Solar panels PV generation system
- 100kW Solis three-phase high-voltage hybrid inverter
- 225kWh LiFePO₄ battery storage system
- 14pcs 51.2V 314Ah battery packs inside
Project Benefits
- Off-Grid Power Supply
Provides independent electricity for a mountain resort hotel without grid access. - Solar Self-Consumption
Uses on-site solar generation directly for daily hotel operation. - Battery Storage for Night Use
Stores daytime solar energy and supplies power when solar generation is low. - Stable Hotel Operation
Supports lighting, guest rooms, pumps, kitchen equipment, reception systems, and other hotel loads.
How to Start Your Project with HBOWA?
Before We Quote, Tell Us 4 Things
Project Location & Grid
Country, grid stability, voltage, frequency, and whether grid connection or power selling is required.
Application Scenario
Backup power / solar storage / peak shaving / demand charge reduction / off-grid / hybrid / microgrid use.
Load & Energy Demand
Daily kWh use, peak power, operating hours, main loads, and whether motors or inductive loads are used.
Site & Special Requirements
Indoor or outdoor installation, available space, existing PV, generator, anti-backflow, EMS, or other special needs.
How HBOWA Handles Your Project
1 Project Location & Grid
We first confirm where the cabinet system will be used and how it connects to the local grid.
2 Application Scenario
Define backup power, solar storage, peak shaving, off-grid, or hybrid use.
3 Load & Energy Demand
Load data helps us calculate cabinet capacity, PCS/ inverter size, backup time, and surge load margin.
4 PV & Existing Equipment
We check whether the storage cabinet needs to work with solar panels, generators, transformers, or existing equipment.
5 Installation Site
Confirm indoor/outdoor installation, cooling method, cable distance, and installation cost.
6 Solution & Quotation
After collecting the project information, HBOWA prepares a practical cabinet solution and quotation for you.
