B&B Solar-Storage-Charging
Integrated Solution
Solar Priority · Storage Peak Shaving · Grid Power Backup
10ms seamless switching | Cut electricity bills by 50%
Four Core Advantages — Directly Solving B&B Pain Points
10ms Seamless Backup Power
Automatically switches over the moment the grid goes down, keeping key equipment like surveillance cameras, refrigerators, and networking running for 8–24 hours — without disrupting the guest experience.
Short-Term Investment, Long-Term Savings
Combining peak-valley rate arbitrage, solar generation offset, and charging pile revenue delivers average annual returns of 27,000 RMB, with net lifetime earnings of 550,000 RMB.
Fast 2–5 Day Installation
A lightweight, modular design that doesn’t damage existing interior finishes and preserves the original grid connection — install and start using it right away.
Intelligent, Unattended Operation
The EMS smart energy management system automatically optimizes the charge/discharge strategy, with remote monitoring via mobile app — no dedicated staff required.

All-Round Protection Worry-Free Operation
↓ Three Cost-Reduction & Efficiency Measures
Smart Energy Dispatch
The EMS system automatically optimizes the charge/discharge strategy, adjusting energy allocation based on occupancy rate.
Modular Configuration
Install solar first and expand storage capacity later; supports tiered battery reuse to cut costs by 30%.
Unattended Operation
Fully automatic operation with remote monitoring and maintenance — no dedicated staff required.
🛡️ Four Risk-Mitigation Solutions
Weather Risk
Grid power serves as a permanent backup; the EMS predicts cloudy/rainy weather in advance and increases off-peak charging.
Electricity Price Volatility Risk
Increasing the share of solar generation and optimizing the arbitrage strategy reduces dependence on price spreads.
Battery Degradation Risk
Premium-grade LiFePO4 batteries with BMS optimization extend battery lifespan.
Equipment Failure Risk
Key components come with a 1-year warranty, and the system is designed with redundancy to ensure continued operation.
