Application Scenarios
Discover how this product can be used in different real-world scenarios
The mid-sized facilities
Who it’s for: Small to medium-sized manufacturing plants, workshops, or agricultural facilities with heavy daytime machinery loads and a need for stable, high-quality power.
Typical loads & priorities (example):
| Load | Power (kW) | Energy Source Priority |
|---|---|---|
| CNC Machines / Welders | 20–40 | 1. Solar / 2. Grid |
| Lighting & HVAC | 5–15 | 1. Solar / 2. Battery / 3. Grid |
| Control Systems & Servers | 1–3 | UPS Backup (Solar/Battery) |
| Diesel Generator (DG) | Up to 50 | Backup for extended outages |
How it runs (Peak Shaving & Backup Mode):
Working Hours: PV → Power all loads; surplus → Charge Battery Evening Peak: Battery → Power essential loads (security, servers) Grid Outage: Battery → Instantly power backup circuits; DG can support/recharge
Sizing guide (for reference):
- A 50 kW / 100 kWh CHS2 system paired with a 100 kWp PV array can cover a significant portion of a factory’s daytime energy needs, saving thousands on electricity bills.
- The 100 kWh battery can provide over 3 hours of full 30 kW backup power, ensuring a safe shutdown or continued operation of critical processes.
“Our electricity bill was our biggest overhead. The CHS2 now covers most of our daytime power, and the backup function has already saved a production batch during a grid fault.”
Commercial Building & Office Park
Who it’s for: Multi-tenant office buildings, retail centers, or private schools that want to reduce common area energy costs, offer EV charging as an amenity, and provide tenants with reliable power.
Typical loads & priorities (example):
| Load | Power (kW) | Energy Source Priority |
|---|---|---|
| Central HVAC System | 15–30 | 1. Solar / 2. Grid |
| Office Lighting & Power | 10–20 | 1. Solar / 2. Battery / 3. Grid |
| Elevators & IT Infrastructure | 5–10 | UPS Backup (Solar/Battery) |
| EV Charging Stations | 22+ | Managed by EMS (Solar/Grid) |
How it runs (Time-of-Use & VPP Mode):
Daytime: PV → Power building loads; surplus → Charge Battery Evening: Battery → Power common areas/security; participate in VPP events Grid Outage: Battery → Instantly power backup circuits (IT, emergency lights)
Revenue guide (for reference):
- A 50 kW / 100 kWh system can significantly reduce a building’s demand charges by shaving peaks.
- By participating in Virtual Power Plant (VPP) programs, the stored energy can be sold back to the grid during high-demand events, creating a new revenue stream.
“The CHS2 was a smart investment. It lowered our operating costs and the VPP income is a welcome bonus. Our tenants appreciate the reliable power and green credentials.”
Remote Community & Off-Grid Resilience
Who it’s for: Remote communities, eco-resorts, or critical infrastructure sites with an unreliable grid connection or a complete off-grid requirement.
System components & roles (example):
| Component | Role |
|---|---|
| PV Array (e.g., 80 kWp) | Primary energy source; powers loads and charges battery |
| CHS2 Battery (e.g., 100 kWh) | Stores daytime energy for night use and cloudy days |
| Diesel Generator (e.g., 50 kW) | Backup source; recharges battery when solar is insufficient |
| Community Loads | Powered 24/7 by the microgrid |
How it runs (Off-Grid Mode):
Sunny Day: PV → Power loads; surplus → Charge Battery Night/Cloudy: Battery → Power loads Low Battery: CHS2 automatically starts DG → Power loads & recharge Battery Full Battery: CHS2 automatically stops DG to save fuel
Resilience guide (for reference):
- A 100 kWh battery can sustain a 10 kW average load for nearly 9 hours without any solar or DG input.
- The intelligent DG control can reduce generator runtime by over 80% compared to a traditional DG-only system, massively cutting fuel costs and emissions.
“We finally have reliable, 24-hour power. The CHS2 runs silently on solar and battery most of the time, and the generator only kicks in when absolutely needed. It’s a game-changer for us.”

Frequently Asked Questions
Find answers to common questions about our products and services
What is CHS2 (30–50 kW) and why do installers choose it for small C&I?
At a glance
- All-in-one cabinet: three-phase hybrid inverter + high-voltage LFP battery + BMS + AC/DC protection.
- Power classes: 30 kW (T4, 4 MPPT) and 50 kW (T6, 6 MPPT).
- Battery options (usable): 51.5 / 64.4 / 77.3 / 90.2 kWh.
- PV side: up to 60 kWp (30 kW) or 100 kWp (50 kW), 180–850 V MPPT, 1000 V max.
Design choices that reduce site time
- Factory-integrated wiring, DC/AC Type II SPD, AFCI, anti-islanding (AFD).
- 6 MPPT option and 22.5 A string current — pairs well with 210-cell high-power modules.
- DG (diesel generator) input and dry-contact control built in.

| Model | MPPT | PV @ STC | Usable battery (kWh) | Cooling / Ingress |
|---|---|---|---|---|
| CHS2-30K-T4-X | 4 | 60 kWp | 51.5–90.2 | Air-conditioned / IP55 (cabinet), IP66 (inverter) |
| CHS2-50K-T6-X | 6 | 100 kWp | 51.5–90.2 | Air-conditioned / IP55 (cabinet), IP66 (inverter) |
How do I plan PV strings and battery size for CHS2?
- Voltage window: 180–850 V MPPT; 1000 V max.
- Per-string current: up to ~22.5 A (supports high-current 210-cell modules).
- Strings per MPPT: 2; balance strings by irradiance and length.
| Pack option | Usable (kWh) | Modules | Charge/Discharge (A) |
|---|---|---|---|
| CB2-57.3-HV5 | 51.5 | 4 | 140 |
| CB2-71.6-HV5 | 64.4 | 5 | 140 |
| CB2-85.9-HV5 | 77.3 | 6 | 140 |
| CB2-100.3-HV5 | 90.2 | 7 | 140 |
Runtime math (simple)
Runtime (h) ≈ Usable battery (kWh) ÷ Load (kW)- 64.4 kWh usable → ~3.2 h at 20 kW essential load.
- 90.2 kWh usable → ~4.5 h at 20 kW; ~1.6 h at 55 kVA peak is not continuous.
What protections and safety layers are built in?
| Layer | What it does |
|---|---|
| AFCI (PV arc-fault) | Cuts DC side on arc signature to reduce fire risk. |
| Type II SPD (DC/AC) | Limits surge energy from lightning or switching events. |
| AFD anti-islanding | Stops feeding a dead grid during outages. |
| RCMU | Residual-current monitoring for leakage detection. |
| Cabinet sensors | CO/smoke/temperature/humidity/water sensors; triggers alarms and protection. |
Everyday effect
- Backup output THDv < 3% for sensitive IT/POS loads.
- 100% three-phase voltage imbalance tolerance on backup.
- Emergency stop and 12 V output available for fast-shutdown accessories.
What backup power can CHS2 deliver, and can I use a diesel generator?
| Model | Backup apparent power | 5-s surge | Voltage / Freq | THDv |
|---|---|---|---|---|
| 30K-T4-X | 33 kVA | 45 kVA | 3L+N+PE, 380/400 V; 50/60 Hz | <3% |
| 50K-T6-X | 55 kVA | 75 kVA | 3L+N+PE, 380/400 V; 50/60 Hz | <3% |
Runtime shortcut
Runtime (h) ≈ Usable battery (kWh) ÷ Average load (kW) 51.5 kWh usable → ~2.6 h @ 20 kW 90.2 kWh usable → ~4.5 h @ 20 kW
