적용 시나리오

이 제품이 다양한 실제 상황에서 어떻게 활용될 수 있는지 알아보세요

도심 홈 오피스: 업무와 학습을 위한 조용한 공간

대상: Apartments or townhouses that need a silent backup for laptops, Wi-Fi, lights, and a fridge while working from home.

Why H2-5k~12k fits: Single-phase hybrid design, wall-mount IP65, low-voltage battery compatibility (40–60 V). Fan noise is low, suitable for indoor utility corners.

권장 백업 팩 (예시):

로드	전력	Hours/day
LED lighting (2–4 rooms)	120–200 W	4~6시간
와이파이 라우터 + CCTV	25–45 W	24시간
노트북 / 소형 PC	60–120 W	6~10시간
냉장고 (인버터 방식)	평균 90–150 W	24시간 (근무)

3가지 간단한 단계:

필수 소켓을 다음 위치로 이동하십시오. 백업 하위 회로; 라벨을 명확하게 표시하십시오.
Set a reserve SOC (e.g., 25–30%) so evening outages still have power.
Run a 2-minute outage test; confirm seamless transfer and load order.

“Power blinked during a call—laptop and Wi-Fi stayed up. No interruption.” — Home worker feedback

H2-5k-12k 저전압 하이브리드 인버터 적용 분야: 도시형 홈 오피스

Suburban House with TOU Tariffs: Cut Bills with Simple Scheduling

대상: Detached houses with 5–10 kW PV looking to shift energy from cheap night rates to the evening peak.

Typical setup: PV 5–10 kW on 2 MPPTs; battery 8–15 kWh (low-voltage pack); backup branch for lights, IT, and a fridge.

How savings happen (simple plan):

Charge (off-peak):  00:00–05:00
Daytime:            PV → House; surplus → Battery
Discharge (peak):   18:00–22:00
Reserve SOC:        25–30%

2 MPPTs handle east/west or south split roofs cleanly.
Use the app to adjust times each season as daylight shifts.
Keep heavy appliances (oven, large compressor) on non-backup.

구성 요소	Recommended	Reason
PV array	5–10 kW	Covers daytime base load + charges battery
Battery	8–15 kWh	2–4 h peak shaving
모드	Self-Use + TOU	Automated schedule; easy to tweak

팁: Check the app’s daily report; if the battery often sits full at noon, slightly extend peak discharge or increase evening loads like laundry.

Small Retail / Clinic (Single-Phase): Keep Sales & IT Online

대상: Street-level shops, clinics, or cafés that run POS, lights, a small fridge, and basic IT—wanting steady service during short grid issues.

Recommended kit:

PV 6–10 kW split across 2 MPPTs (east/west or south split)
Battery 10–16 kWh for evening hours
Backup branch: POS, lighting, router/CCTV, small freezer

Energy flow (typical day):

Time block	Flow	Note
Morning–Afternoon	PV → Loads; surplus → Battery	Covers base load while open
Evening	Battery → POS, lights, IT	Smooth checkout during peak
Outage	Seamless backup output	No reboot on POS/router

Quick continuity checklist:

Label backup vs non-backup circuits at the board.
Keep high inrush appliances (big compressor, ovens) on non-backup.
Run a 10-minute test with the site open; check card terminals and printers.

“Short brownout—POS never dropped, customers didn’t notice.” — Store owner

자주 묻는 질문

당사의 제품 및 서비스에 관한 자주 묻는 질문에 대한 답변을 확인해 보세요

How do I choose between 5k, 6k, 7.6k, 8k, 10k, and 12k for my site?

Quick idea: pick by daytime peak load + roof PV space; size battery by evening use hours.

Site type	Peak load	Inverter	PV (typ.)	Battery (2–4 h)
Home + home office	3–6 kW	5–6 kW	5–8 kW	7–12 kWh
Villa / small shop	6–10 kW	7.6–10 kW	8–12 kW	10–20 kWh
Clinic / café with IT	8–12 kW	10–12 kW	10–16 kW	12–24 kWh

What the H2-5–12k LS2 gives you: 2 MPPTs for split roofs (90–480 V MPPT), IP65 wall-mount, quiet ≤50 dBA, single-phase grid. Use high-current strings within the model limits. :contentReference[oaicite:0]{index=0}

Checklist before you lock size:

List 5 critical loads you want alive in outages (backup branch).
Count roof strings for 2 MPPT distribution; keep within 500 V DC max and current limits per model. :contentReference[oaicite:1]{index=1}
Confirm local grid profile and breaker size (see FAQ 5 table).

What’s in the box, and which documents will I receive?

Typical package (by model):

Item	Use
Hybrid inverter	PV + battery controller
Communication module (Wi-Fi/4G)	App/portal connectivity
CT (external)	Metering & energy flow sensing
Terminal kit, battery temp sensor	Clean wiring / lead-acid temp comp.
Mounting hardware + hole template	Fast wall install
Documents pack	Quick Guide, User Manual, Warranty

Sunriver Electric supplies the latest digital PDFs (datasheet, quick guide, user manual) on request to speed up approvals and site prep. :contentReference[oaicite:2]{index=2}

Before installation:

Inspect carton for damage; verify exact model on the label.
Lay out connectors separately to avoid cross-wiring.
Read safety notes; install only by qualified electricians.

팁: keep the hole-positioning paper; it speeds drilling and keeps clearances correct for cable entry. :contentReference[oaicite:3]{index=3}

What batteries can I use, and how big should the pack be?

Battery types: LiFePO₄ or lead-acid, low voltage 40–60 V. Use BMS CAN/RS485 mapping for lithium; connect the temp sensor for lead-acid. :contentReference[oaicite:4]{index=4} :contentReference[oaicite:5]{index=5}

Model range: H2-5K/6K/7.6K/8K/10K/12K-LS2; check per-model charge/discharge current in the datasheet when finalizing packs. :contentReference[oaicite:6]{index=6}

Simple sizing (examples):

Use case	Evening load	Battery (kWh)
Home + fridge + IT	1.5–2.5 kW × 3 h	6–8
Villa / small shop	2–4 kW × 3–4 h	10–16
IT-heavy home office	1–2 kW × 6 h	8–12

Connection notes:

Use the correct battery cable size (up to 0 AWG on 10 kW); torque to spec. :contentReference[oaicite:7]{index=7}
Insert via BAT gland to BAT+/BAT− terminals; add isolator ≥70 A if required by local code. :contentReference[oaicite:8]{index=8}
For lithium, wire BMS to BMS_CAN; for lead-acid, connect the temp sensor to COM1. :contentReference[oaicite:9]{index=9}

How does backup work, and what should go on the backup branch?

The inverter switches to battery and keeps critical loads running immediately and seamlessly during a grid outage. This avoids flicker or reboots on essential circuits. :contentReference[oaicite:10]{index=10}

Put on BACK-UP: LED lighting, router/CCTV, laptops/PCs, fridge (inverter type).

Keep on non-backup: EV charger, large ovens, big compressor motors (inrush current). :contentReference[oaicite:11]{index=11}

모드	AC output (backup)	THDv
H2-5–12k LS2	up to rated VA, 60 s peak headroom	<3% (linear load)

Use the separate BACK-UP terminals shown in the junction box; label the backup sub-board clearly. :contentReference[oaicite:12]{index=12}

What AC breaker and cable sizes should I prepare (by model)?

Grid-side breaker & cable (from Quick Guide):

Model	AC breaker	Cable size (L/N)
H2-5K-LS2	50 A	8 AWG
H2-6K-LS2	63 A	8 AWG
H2-7.6/8K-LS2	80 A	8 AWG
H2-10K-LS2	100 A	6 AWG

Notes:

Keep total voltage drop ≤2% from point of grid connection; upsize cable if the run is long.
Strip lengths: 20 mm for LOAD/GRID, 10 mm for GEN; torque to the listed values in the guide. :contentReference[oaicite:13]{index=13}
Follow local codes for breaker curves and RCD selection.

How do I commission and monitor with the Elekeeper app?

Download Elekeeper (iOS/Android). Choose language and Overseas Node; register if needed. :contentReference[oaicite:14]{index=14}
Local connect via Bluetooth → select inverter SN → run the Initialization wizard. :contentReference[oaicite:15]{index=15}
Set battery brand/mode, wiring (with/without meter/CT), and country/grid compliance profile. :contentReference[oaicite:16]{index=16}
Join Wi-Fi/Ethernet/4G for remote monitoring; create the plant for the owner. :contentReference[oaicite:17]{index=17}

What you can do daily: check PV/battery/load flow, SOC, alarms; switch modes (Self-Use / Backup / TOU); view reports; update firmware when prompted. :contentReference[oaicite:18]{index=18}

Simple TOU schedule (example):

Charge (off-peak): 00:00–05:00
Discharge (peak):  18:00–22:00
Reserve SOC:       25–30%

If Italy: run the built-in CEI 0-21 self-test and save the report from the app. :contentReference[oaicite:19]{index=19}
