Overview
The HYBRID AIO BESS is a highly integrated smart energy solution that deeply combines PV power, energy storage, diesel generator backup, and smart grid interaction capabilities. Through the integration of hardware (including energy storage batteries, PCS, MPPT, and STS) and intelligent energy management software, the system enables dual operational modes: "on-grid for energy savings and off-grid for backup power."
It establishes a 3-tier power supply structure prioritizing solar energy, buffered by storage, and backed up by diesel generation. In the event of grid anomalies, the system achieves seamless transition to off-grid microgrid operation within 10 milliseconds, ensuring zero-interruption power supply for critical loads, making it especially suitable for scenarios with extremely high requirements for power continuity.
When connected to the grid, the system prioritizes solar power, uses stored energy to shave peak loads, and keeps the generator as a last-resort backup, enhancing efficiency and cutting costs. When operating independently off-grid, it intelligently coordinates solar generation, battery storage, and the generator to optimally distribute energy, significantly saving fuel and reducing operational expenses.
The system supports 3 modes: on-grid, off-grid, and seamless switching, enabling participation in grid interactions or operation as an independent microgrid. This significantly enhances energy autonomy and disaster resilience. Its integrated design greatly simplifies installation and commissioning, reduces coordination costs and operational complexity, making it suitable for various scenarios such as remote areas, base stations, factories, and islands.
System Topology
Applications
Self-Consumption
when solar > loads:
solar power up loads + charge battery +/ or feedback to the grid
when solar< loads: solar + battery +grid (when battery isn't sufficient) to power up loads
when there is no solar: battery fully discharged, no grid avaivable, BESS starts up diesel automatically as final backup
- Maximize Solar Utilization
- Increase energy independence and reduce utility bills. The BESS stores excess solar energy generated during the day for use during the night or peak hours, maximizing the consumption of your own green power.
- Solar Peak: BESS charges using surplus solar power that exceeds the immediate load demand.
- Solar Valley: BESS discharges to power the facility when solar generation is unavailable, reducing grid reliance.
Where the main grid fails suddenly:
Normal State: BESS (Battery Energy Storage System) stays on standby, monitoring the grid power. If PV (Solar) is available, it charges the battery; if not, it just waits.
When blackout happens: BESS detects the power loss instantly and takes over the power supply to the loads within <10ms (seamless transfer).
When solar is available: BESS powers up the loads directly with solar energy and uses the extra power to charge the battery.
When solar is not enough/too dark: BESS discharges the battery to power up the loads continuously.
When battery becomes low: (If diesel generator is equipped) BESS automatically starts up the diesel generator as the final backup to keep loads running.
Back Up
When power outage: (<10ms transfer time from on grid to off grid)
when solar > loads: solar power up loads +charge battery
when solar< loads: solar + battery to power up loads
when there is no solar, battery becomes low, BESS starts up diesel automatically as final backup
- Reliable Power Assurance
- Safeguard against unexpected outages with a reliable power reserve. The BESS provides a stable and clean power source to prevent data loss and operational downtime.
- Outage Event: BESS activates instantly to maintain power continuity for mission-critical equipment.
- Standby Mode: BESS remains on standby, maintaining full charge readiness for the next emergency.
Micro-grid
Where there isn't grid net at all:
when solar >loads: solar power up loads +charge battery
when solar< loads: solar + battery to power up loads
when there is no solar, battery becomes low, BESS starts up diesel automatically as final backup
- Islanded Operation & Grid Resilience
- Operate independently or in conjunction with the main grid. The BESS stabilizes the local micro-grid, balancing supply and demand while enabling seamless transition to island mode.
- Grid-Connected: BESS optimizes energy flow within the micro-grid, reducing overall energy costs.
- Island Mode: BESS forms the grid backbone, maintaining stable voltage and frequency for all connected loads during main grid disconnection.

Frequently Asked Questions
The Hybrid AIO BESS deeply integrates PV power, energy storage, diesel generator backup, and smart grid interaction into a single all-in-one unit. Unlike standard BESS that only stores energy, this system manages three energy sources (solar, battery, generator) with intelligent dispatching, enabling "on-grid for savings, off-grid for backup" operation with seamless 10ms switching.
The system prioritizes: ① Solar power for immediate load consumption, ② Battery storage for buffered energy and peak shaving, ③ Diesel generator as the final backup. In grid-connected mode, solar powers loads first, excess charges the battery, and the generator stays idle. During outages, the system switches to off-grid microgrid mode within 10ms, maintaining zero-interruption power to critical loads.
Yes. The Hybrid AIO BESS has Grid-Forming and Black Start capabilities, allowing it to autonomously establish a stable AC microgrid in areas without grid power. It coordinates solar generation, battery storage, and diesel generators to optimally distribute energy, making it ideal for remote areas, islands, and off-grid industrial sites.
No. The system detects grid anomalies and switches to off-grid mode within 10ms via the built-in STS (Static Transfer Switch). This is fast enough that sensitive equipment — including servers, medical devices, and precision instruments — experience no interruption or restart.
Three mechanisms: ① Self-consumption — maximize use of cheap solar power instead of buying from the grid, ② Peak shaving — discharge battery during expensive peak tariff periods to reduce maximum demand charges, ③ Grid services — participate in demand response programs and earn revenue from grid stabilization services.
