Before You Buy
Pre-Order FAQsHow large and heavy is the PowerSkit 5, and how is it installed?
The PowerSkit 5 is a compact 3U, 19-inch rack unit measuring 148 × 449 × 510 mm and weighing 50 kg (steel chassis).
- It slides straight into a standard 19-inch server rack — no shelf bracket and no cabinet rework required. A built-in 125 A circuit breaker provides a physical isolation point.
- Cooling is passive and fanless — no fans to clean and no fan noise.
- It operates from 0°C to +55°C while charging and -25°C to +55°C while discharging, tolerates up to 95% RH non-condensing humidity and 3,000 m altitude. The enclosure is IP21, for indoor installation.
- A heating pad is available as an option — order it with the unit if your site needs one.
Which inverters is the PowerSkit 5 compatible with?
The PowerSkit 5 is designed to work with a wide range of hybrid and off-grid inverters. It communicates over CAN, RS485, RS232 and Wi-Fi, plus a dry-contact output. RS485A/CAN go to the inverter, while RS485B/RS485C coordinate communication between parallel units.
During commissioning, select the corresponding lithium battery protocol in your inverter's menu so voltage and current limits follow the battery BMS.
The Wi-Fi module is an optional external accessory — the battery ships without it unless ordered. With it installed, the battery streams data to the Gobel VRM platform and integrates with Home Assistant and ioBroker; Bluetooth is available for on-site monitoring.
If you need a confirmed compatibility list for a specific inverter brand or model, please contact [email protected] with your inverter model and we will confirm the setup.
Can I connect multiple PowerSkit 5 units to expand capacity?
Yes. The PowerSkit 5 supports up to 16 units connected in parallel — up to 81.92 kWh total — so you can start with one 5.12 kWh 3U unit and expand as your energy needs grow.
- Series connection is not supported — always parallel, never stack voltages.
- RS485B/RS485C ports coordinate communication across the parallel bank, and each unit reports its own status over the communication port.
If you plan a multi-unit system, tell us the total capacity you need and we will advise on cabling and configuration: [email protected].
How long does delivery of the PowerSkit 5 take, and which shipping terms do you support?
The PowerSkit 5 ships from our China warehouse. Typical door-to-door delivery time is 30-50 days, depending on your destination and the shipping method chosen at quotation.
We can quote under the standard trade terms:
- EXW (ex-works, you arrange freight)
- FOB (free on board)
- CIF (cost, insurance and freight)
- DDP (delivered duty paid)
For an exact lead time and freight quote to your port or address, contact [email protected].
What warranty does the Gobel PowerSkit 5 come with?
The PowerSkit 5 carries a 5-year warranty, extendable to 10 years (PRO), covering defects in materials and workmanship of the battery pack and its built-in BMS under normal use. The design life is rated at 10+ years.
The applicable warranty period and terms depend on the purchase agreement confirmed at order time. For the detailed warranty document, register or inquire at [email protected] with your order number.

Product Detailed Introduction
Comprehensive mechanical architecture, internal protection systems, and technical guidelines.
Solar Battery Rack Slide it in. 5.12 kWh of LiFePO4.
A 3U 19-inch rack battery with 100 Ah of prismatic LiFePO4 at 51.2 V, a JKBMS JK100 BMS with built-in 125 A circuit breaker and aerosol fire suppression, and Gobel VRM monitoring — slide it in, connect it, power up.
48V Solar Battery 51.2 V nominal. 100 Ah. 5.12 kWh.
The PowerSkit 5 is a true 48V-class battery: 51.2 V nominal across a 44.8–57.6 V operating window, 100 Ah and 5.12 kWh per 3U unit. It charges and discharges at 100 A continuously — 130 A for 25-second peaks — delivering 5.12 kW of continuous output and 6.66 kW of peak power for demanding loads.
- 51.2 V nominal · 44.8–57.6 V operating window
- 100 A continuous charge and discharge · 130 A peak (25 s)
- 5.12 kW continuous output · 6.66 kW peak power (25 s)
- 100% depth of discharge — the full 5.12 kWh is usable
LiFePO4 Solar Battery 6,000+ cycles. 16 MWh throughput.
Sixteen prismatic LiFePO4 cells in a 16S1P configuration, kept in step by a 2 A bidirectional active balancer that makes every cell age together. Rated for at least 6,000 cycles at 100% DOD (70% EOL) — 16 MWh of energy throughput — this is a battery built to cycle daily for well over a decade.
- 16S1P pack of brand-new prismatic LiFePO4 cells

Solar Battery Backup for Home Your loads keep running when the grid doesn't.
When the grid fails, the JK100 BMS takes over: over-voltage, over-current, over-temperature and short-circuit protection run continuously, a 125 A built-in circuit breaker gives you a physical isolation point, and an integrated aerosol fire-suppression module watches over the cells. Charging is rated from 0 °C to +55 °C, discharging down to −25 °C.
- JKBMS JK100 BMS — voltage · current · temperature · short-circuit protection
- 125 A circuit breaker built in for safe isolation
- Integrated aerosol fire suppression
- IP21 indoor enclosure — passive, fanless, silent
- Optional heating pad for cold-climate installs
Off Grid Solar Battery System CAN, RS485, RS232, Wi-Fi — talk to any inverter.
