Where This Model Fits Best
Use these scenarios to decide whether this model belongs on the shortlist before quote approval.
Solar EV Charging & Home Backup
Who it’s for: Homeowners with an Electric Vehicle who want to maximise clean energy use, charge their car with sunshine, and secure essential power during outages.
Key loads & priorities (example):
| Load | Power (W) | Prioridad |
|---|---|---|
| EV Charger | Up to 7,400 | 1 (when surplus PV is high) |
| Home Office & Fridge | 200–400 | 2 (always on, UPS backup) |
| General Household | 500–2000 | 3 (covered by PV/battery) |
How it runs (Self-Use + EV Mode):
Sunny Day: PV → House; surplus → EV Charger; extra → Battery Cloudy Day: PV → House; Battery tops up loads Evening: Battery → House; (optional: top up EV from battery/grid) Grid Outage: Battery → Backup circuit (lights, fridge, office)
Charging guide (for reference):
- A 10 kWh battery system can add ~35-45 km of range to an EV overnight from stored energy alone.
- With 6 kW of PV panels, a full sunny day can provide over 30 kWh of energy—enough for a full charge on many standard-range EVs.
Do/Don’t for the backup branch:
| Put on BACK-UP | Keep on non-backup |
|---|---|
| Lights, router, fridge, home office, security | EV Charger, AC unit, oven, water heater |
Cut Evening Bills & Beat Peak Tariffs
Who it’s for: Families with high energy use after sunset who want to slash their electricity bills by avoiding expensive peak-hour grid tariffs.
Typical evening loads (example):
| Load | Power (W) | Energy Use (4h) |
|---|---|---|
| Kitchen (cooking, microwave) | 1200–2000 | ~1.5 kWh |
| Entertainment (TV, console) | 200–400 | ~1.0 kWh |
| Lighting & General Use | 150–300 | ~0.8 kWh |
| Total Evening Use | – | ~3.3 kWh |
How it runs (Time-of-Use Mode):
Daytime (Off-Peak): PV → House; surplus → Battery 17:00–21:00 (Peak): Battery → House; avoid grid import Night (Off-Peak): Grid → House; (optional: charge battery on cheap tariff)
Sizing guide (for reference):
- A 5 kWh battery pack (4.5 kWh usable) easily covers a typical 3–4 kWh evening peak, making the home self-sufficient when grid costs are highest.
- A 10 kWh system provides a larger buffer for heavy-use days or cloudy weather.

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.
