Where This Model Fits Best
Use these scenarios to decide whether this model belongs on the shortlist before quote approval.
The High-Consumption Smart Home
Who it’s for: Large modern homes with three-phase power, high energy demands (pool pumps, multiple air conditioners, home offices), and an EV, seeking maximum energy independence and a premium, integrated solution.
Typical high-demand loads (example):
| Load | Power (W) | Priority |
|---|---|---|
| Central Air Conditioning | 3000–5000 | Run on solar/grid |
| EV Charger | Up to 11,000 | Charge with surplus solar |
| Pool Pump | 800–1500 | Run on solar |
| Kitchen & Essentials | 500–2500 | UPS Backup |
How it runs (Self-Use + EV + Backup Mode):
Daytime: PV → Power all loads; surplus → Charge EV; extra → Charge Battery Evening: Battery → Power entire home Grid Outage: Battery → Seamlessly power essential circuits (<20ms switch) Set Reserve: Keep Battery SOC at 25% for outage protection
Sizing guide (for reference):
- A 15 kWh battery system (3 modules) can comfortably cover a high-use evening (6-8 kWh) while retaining ample backup power.
- A 25 kWh system (5 modules) provides true multi-day energy security for the whole home.
Small Commercial & Workshop Resilience
Who it’s for: Small businesses, workshops, or agricultural operations with three-phase machinery and critical systems (like refrigeration, servers, or automated equipment) that need to cut daytime energy costs and ensure operational continuity.
Critical business loads (example):
| Load | Power (W) | Put on BACK-UP? |
|---|---|---|
| Office Server & Network | 200–350 | Yes |
| Refrigeration / Cold Room | 1500–3000 | Yes |
| Lighting & Security | 300–600 | Yes |
| Heavy Machinery | 5000–10000+ | No (keep on grid) |
How it runs (Backup & Self-Use Mode):
Daytime: PV → Power all loads (office + machinery); surplus → Battery Grid Outage: Battery → Instantly powers backup circuit (office, refrigeration) Evening: Battery → Powers essential overnight loads (servers, security) Set Reserve: Keep Battery SOC at 50% minimum for business-hour backup
Runtime guide (for reference):
- A 10 kWh battery pack can run a 2 kW critical load for over 4 hours, bridging most common power cuts.
- A 25 kWh system (5 modules) provides extended resilience for a full working day’s essential operations.

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.
