Technical Overview
Quick answer: The SR5000 is an all-in-one balcony solar energy storage system (ESS) that combines a 5,120 Wh LiFePO₄ battery, a 2,400 W hybrid inverter, and dual MPPT solar charge controllers (1,000 W per channel) in a single IP65-rated unit, delivering plug-and-play home battery backup with a 10 ms UPS switchover and a 6,000-cycle battery life.
What is the SR5000?
The SR5000, manufactured by Kunlu Electronic Technology (Shanghai) Co., Ltd., is an all-in-one solar ESS designed for balcony and small residential photovoltaic installations. It integrates battery storage, PV charging, grid connection, and off-grid backup into one floor-standing enclosure measuring 520 × 181 × 715 mm and weighing 59 ± 2 kg. The system stores 5.12 kWh of electricity—enough to run a refrigerator, router, and essential household loads through an outage or an expensive peak-tariff window.
Key Technical Specifications
| Parameter | Value |
|---|---|
| Battery type / rated capacity | LiFePO₄, 100 Ah @ 51.2 V (5,120 Wh) |
| Battery operating voltage | 44.8–58.4 V |
| Max charge / discharge current | 60 A / 60 A |
| Cycle life | 6,000 cycles (≈15-year lifespan) |
| PV input | 2 channels, 10–100 V, 1,000 W × 2 (max 2 kW) |
| Grid-connected output | 800 W default / 2,400 W max, 230 V, 50 Hz |
| Off-grid output | 2,400 W continuous, 10.9 A |
| UPS switchover time | < 10 ms |
| Protection rating / temperature | IP65 / −20 °C to +60 °C |
| Communication | Wi-Fi, Bluetooth, RS485 |
How Does the SR5000 Handle Solar Charging?
The system provides two independent MPPT channels, each accepting 10–100 V DC with up to 16 A input current and 1,000 W of panel power. This dual-MPPT architecture lets it connect two separate balcony solar strings with different orientations while maximizing harvest from each. It is compatible with any PV module within the voltage window.
What Happens During a Power Outage?
When the grid fails, the SR5000 switches to off-grid mode in under 10 milliseconds—faster than a computer or router reboot—keeping essential loads running without interruption. The off-grid AC port delivers 2,400 W continuous at 230 V.
Can Capacity Be Expanded?
Yes. Up to four SR5000 units can operate in parallel, scaling storage to 20.48 kWh for larger households or EV backup.
Smart Features and App Control
The Voltdeer app provides remote monitoring of battery level, PV yield, and grid status; OTA firmware upgrades; timed charge/discharge scheduling; and an AI mode that combines electricity prices and weather forecasts to auto-generate daily energy plans. A built-in heating film enables safe charging and discharging at temperatures down to −20 °C.
Certifications and Grid Compliance
The SR5000 is certified to CB (IEC 62619, IEC 60730-H), CE-LVD (IEC 62109-1/2, IEC 62477-1), CE-EMC, CE-RED, RoHS, REACH, WEEE, UN38.3, and grid standards EN 50549-1/10, C10/11, VDE 4105, and CEI 0-21—covering German, Italian, Spanish, and pan-European grid codes. It pairs with Shelly and Voltdeer smart meters (SMeter-RS02 / SMeter-RC01).
FAQ
Is the SR5000 weatherproof? Yes, IP65-rated for dust and water-jet resistance, suitable for outdoor balcony mounting.
How long does the battery last? 6,000 cycles at rated conditions, roughly a 15-year design life.
What is the warranty-relevant chemistry? Lithium iron phosphate (LiFePO₄), the thermally stable chemistry standard for home storage.
SR5000 versions
Both SR5000 versions provide 5.12 kWh of storage. SR5000 connects directly to solar PV panels; SR5000 AC PRO connects to an existing solar system through a microinverter.
