Where This Model Fits Best
Use these scenarios to decide whether this model belongs on the shortlist before quote approval.
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.
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.
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.

FAQ for Technical Review
Use these questions to resolve monitoring, warranty, compatibility, and procurement concerns before approval.
How do I choose between HS2, HS3, and CHS2?
Start with application scope and capacity path. HS2 and HS3 usually fit residential or light-commercial integrated storage paths, while CHS2 is the stronger route when the project is clearly C&I and needs larger cabinet-scale storage.
What capacity and backup details matter before approval?
Confirm target capacity, backup expectation, phase, and whether the project needs integrated EMS or accessory coordination. These details usually decide whether the shortlist stays in residential ESS or moves into a higher-output commercial path.
What site or installation details should I send with the inquiry?
Share the destination market, installation type, expected quantity, and any constraints around footprint, commissioning, or monitoring. That helps Sunriver keep the document pack and quote route aligned with the real deployment condition.
Which file should I review first for an all-in-one ESS project?
Use the datasheet first to confirm power, capacity, configuration, and family fit. Move to the user manual or quick guide when the conversation reaches installation sequence, commissioning, or training handoff.
What helps Sunriver respond faster with pricing and support direction?
Send the target model or family, project type, phase, capacity range, destination country, and expected schedule. If the buyer also needs battery, warranty, or support routing details, include that in the first request so the follow-up stays concise.
