Application Scenarios

Home Studio: Quiet, Clean Power for Recording & Streaming

Who it’s for: Creators who need steady, silent power for DAWs, audio interfaces, microphones, LED lights, and streaming gear—without pops, reboots, or fan noise.

Why HS2 fits: All-in-one stack keeps wiring short and tidy; seamless backup prevents audio dropouts during grid blips; quiet operation suits indoor studios.

Suggested backup map:

Device Typical power Backup? Notas
Audio interface + preamps 10–35 W Yes Avoid USB reconnect mid-take
Studio PC / laptop 120–300 W Yes Protects DAW session from crash
Nearfield monitors (pair) 40–120 W Yes (mixing) Mute during transfer test to avoid thumps
LED key/fill lights 20–80 W Opcional Low surge, stable color temp
HVAC / heater / kettle kW-class No Keep off backup to avoid inrush

Noise & grounding checklist:

  • Place the ESS stack outside the live room (utility corner/closet).
  • Run a single backup power strip for only studio gear to minimize ground loops.
  • Separate audio and lighting cables; cross at 90° if they must meet.
  • Do a 2-minute outage test; watch for pops, clicks, or USB reconnects.

Simple daily schedule (recording day):

09:00–17:30  PV → Studio + charge battery
17:30–22:00  Battery → PC, interface, monitors, LEDs
Always       Reserve SOC 25–30% for late sessions

Quick sizing hint (example only): A 10 kWh usable pack can support ~300–350 W of studio essentials for ≈24–28 hours total runtime (spread across sessions).

“A power blink used to ruin takes; now the meters don’t even twitch.” — Producer, home studio

HS2-3k-6k-all-in-one-energy-storage-solution-Home Studio
Urban Home Office: Quiet Backup for Work & Study

Who it’s for: Apartments or townhouses that need silent, space-saving backup for laptops, Wi-Fi, lighting and a fridge during short grid issues.

Why HS2 fits: All-in-one stack (inverter + BMS + batteries) → fewer conduits; compact footprint for utility nooks; low audible noise for indoor walls.

Suggested backup pack (example):

Load Power Run time target
LED lighting (3–5 rooms) 150–250 W 4–6 h
Wi-Fi router + CCTV 30–60 W 24 h
Laptop / small PC 60–120 W 6–10 h
Fridge (inverter type) 90–150 W avg 24 h (duty)

3 quick steps:

  1. Move essential sockets to the BACK-UP sub-circuit; label clearly.
  2. Set a reserve SOC (e.g., 25–30%) to keep evening buffer.
  3. Run a 2-minute outage test; confirm no flicker or device reboot.
Simple daily plan:
Daytime:      PV → Loads; surplus → Battery
Evening peak: Battery → Lights/IT (18:00–22:00)
Night buffer: Reserve SOC 25–30%

“Power dipped mid-call — laptop and Wi-Fi stayed up. Zero interruptions.”

Frequently Asked Questions

Find answers to common questions about our products and services

What should I prepare on-site so installation is fast and clean?

Goal: a one-visit install with tidy wiring and zero callbacks. Do these before your electrician arrives.

Area What to get ready
Mounting location Flat wall or base stand; dry, ventilated utility space; clear cable path to DB and roof strings
Board planning Decide which circuits move to BACK-UP (lights/IT/fridge). Label backup vs non-backup in advance
Conduits & routing Pre-run AC, PV, and battery conduits with pull lines; leave 15–20% spare space for future add-ons
Network Wi-Fi SSID/password or Ethernet drop near the unit for app/portal access

Pre-flight (5 steps):

  1. Mark drill holes with the template; verify vertical clearance for future battery additions.
  2. Stage connectors by circuit (PV / BAT / GRID / BACK-UP) to avoid cross-wiring.
  3. Print a one-page list of loads going to BACK-UP and tape it on the board.
  4. Prepare the router login; check signal at the install spot.
  5. Plan a 2-minute outage test for handover (evening or after business hours).

Common mistakes to avoid:

  • Putting high-inrush devices (OVEN/large compressor/EV charger) on BACK-UP.
  • Routing PV and data cables in the same metal conduit without separation.
  • No labels on backup sockets → users plug heavy tools there by accident.

“Site prepped like this cuts commissioning time by half.” — Installer note

What support does Sunriver Electric provide around HS2 projects (from quote to shipment)?

Focus: make procurement simple and predictable for installers and distributors — clear choices, clean docs, and transparent shipping info.

Stage What you get Why it helps
Model matching & quote FOB pricing and model suggestions aligned to your load profile and roof layout Speeds up decisions; avoids over/under-sizing
Documentation pack Latest datasheet, Quick Guide, User Manual, and test certificates (digital PDFs) Smooth utility filings and internal approvals
Pre-shipment checklist Packing list with SNs, carton specs & gross weight; outer-box label sample; loading photos on request Faster warehouse check-in; better traceability
After-shipping updates Vessel/flight info and B/L or tracking number; exception alerts if delays occur Transparent progress; easier site scheduling

On request:

  • Simple wiring overview (for team briefing before installation)
  • FAQ kit (backup branch planning, TOU examples, commissioning checklist)
  • Certificate language packs (e.g., English/Spanish/Thai)

How to speed up your quote (send these 6 bullets):

  1. Site type and peak loads (home/shop/clinic; evening vs daytime)
  2. Roof plan (two MPPT splits, rough panel count if known)
  3. Target backup circuits (lights/IT/fridge etc.)
  4. Desired battery capacity (usable kWh) or runtime goal
  5. Country/grid standard for compliance docs
  6. Target ship week and destination port
Tip: if you already purchased meters/CTs or comm sticks, include their models so we can confirm compatibility in one pass.

Contact: sales@sunriver-electric.com — reply with the six bullets above and we’ll return a clean, ready-to-use pack.

How do I design the backup circuit for everyday outages?

Goal: keep essentials alive (lights, Wi-Fi, IT, fridge) without tripping on motor inrush. Put only steady loads on BACK-UP.

Example backup plan (for a typical home/shop):

Load Approx. power Run time goal Notas
LED lighting (3–5 rooms) 150–250 W 4–6 h Low surge
Router + CCTV 30–60 W 24 h Continuity matters
Laptop / POS / small PC 60–150 W 6–10 h Critical work
Fridge (inverter type) 90–150 W avg 24 h (duty) Food safety
Runtime sanity check (example only): A ~10 kWh usable pack can support ≈400 W essentials for ~20–22 h. If you need longer, reduce loads or add modules.
  1. Move essential circuits to BACK-UP terminals; label the sub-board.
  2. Set a reserve SOC (e.g., 25–30%) so evening outages still have cover.
  3. Do a 2-minute grid-off test; confirm no device reboots or flicker.
What’s the fastest commissioning path on day one?
  1. Mount the base + inverter enclosure; keep clearances for ventilation and cable glands.
  2. Wire AC GRID and BACK-UP to the board; land PV strings to the two MPPT inputs; connect the battery harness.
  3. Power up DC/AC → open the mobile app → bind device by SN via Bluetooth.
  4. Select country/grid profile; pick working mode (Self-Use / TOU / Backup) and set reserve SOC.
  5. Join Wi-Fi/Ethernet/4G for remote access; create the plant for the owner; check live power flow.

5-minute handover checklist:

  • Screenshots of final settings (grid profile, reserve SOC, schedules)
  • One grid-off test recorded in the app
  • Labels on BACK-UP vs non-backup circuits
How do I expand battery capacity later without headaches?

Plan for growth: start with what the client needs now (e.g., 10 kWh usable) and add modules as evening use grows.

Expansion workflow (summary):

  1. Schedule downtime; power down per manual; isolate AC and PV/DC.
  2. Add the new battery module(s) to the stack; follow the alignment & fastening steps.
  3. Reconnect harnesses; power up; in the app, confirm the new total capacity.
  4. Run a short charge/discharge to ensure modules report correctly.

Good practice: install modules from the same series and keep SOCs close (±5–10%) before coupling, to minimize balancing time.

What can I see in the app, and how does it help owners and O&M?
At a glance: live PV → Load → Battery → Grid flow, battery SOC, daily yield/consumption, and alerts.

Daily actions (simple):

  • Switch modes: Self-Use / Backup / Time-of-Use
  • Set reserve SOC (e.g., 25–30%) to protect evening hours
  • Adjust TOU windows when seasons change
  • Share viewer access with the homeowner or store manager
  • Apply firmware updates without a site visit

Reporting: download monthly energy and savings summaries; useful for utility audits and O&M reviews.
