Where This Model Fits Best
Use these scenarios to decide whether this model belongs on the shortlist before quote approval.
Suburban House with Heat Pump & Laundry (TOU Savings + Backup)
Who it’s for: Detached homes that want lower evening bills and seamless backup for lights/IT while running a heat pump and daily laundry.
| Component | Recommended | Why |
|---|---|---|
| PV array | 6–10 kW (2 MPPT, split E/W or S) | Covers daytime base load + charges battery |
| Battery stack | 10–16 kWh usable | 2–4 h evening peak shaving + outage buffer |
| Backup branch | LEDs, router/CCTV, work PC, fridge | Seamless transfer (UPS-class) without reboots |
Simple TOU schedule (example):
Charge (off-peak): 00:00–05:00 Daytime: PV → Loads; surplus → Battery Discharge (peak): 18:00–22:00 Reserve SOC: 25–30%
Installer checklist:
- Put heat pump/washer on non-backup; keep backup for steady loads.
- Label backup sockets clearly to avoid accidental heavy tools usage.
- Run a 2-minute outage test at sunset to verify switchover and runtime.
EV-Ready Home: Peak Shaving + Off-Peak Charging (Single-Phase)
Who it’s for: Homes that want to control evening bills while charging an EV at night. EV charger stays on non-backup; house essentials sit on backup.
House vs EV — simple split:
| Circuit | What’s on it | Reason |
|---|---|---|
| BACK-UP | LEDs, router/CCTV, work PC, fridge | No flicker/reboot during grid blips |
| NON-BACKUP | EV charger (10–16 A), oven, AC compressor | Avoid high inrush on transfer |
Daily schedule (example):
House battery: Charge 00:00–05:00; Discharge 18:00–22:00; Reserve SOC 25–30% EV charging: Start 00:30 @ 10–16 A (off-peak); stop by 05:30 Notes: Keep EV on non-backup; label sockets to avoid mix-ups
Rural Café / Clinic (Unstable Grid): Quiet Backup Without a Genset
Who it’s for: Sites with frequent dips/short cuts that still need lights, Wi-Fi/EMR, and a small fridge to keep operating calmly.
| Time | Energy flow | Note |
|---|---|---|
| Morning–Afternoon | PV → Loads; surplus → Battery | Quiet operation, indoor-friendly |
| Evening | Battery → Lights/IT | No genset noise/fumes |
| Grid outage | UPS-class transfer | POS/EMR stays online |
Wiring quick path:
- Move LEDs, router/EMR PC, small fridge to BACK-UP.
- Keep coffee machines/ovens on non-backup (high inrush).
- Mark the board and run a 2-minute outage test for staff training.
Noise & placement: Locate the stack in a back room; low audible noise suits patient areas and small dining rooms.

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.
