Gobel PowerFable 16 Server Rack Battery 16kWh 51.2V 314Ah

Both versions are the same 51.2V 314Ah server rack pack with a 200A BMS and a built-in 2A active balancer. What changes is how you reach the BMS and how a parallel bank addresses itself.

JK BMS (JK200, PB16S2A2P)

• Onboard Bluetooth — the JK BMS app connects straight to the pack, no extra hardware.
• Manual DIP addressing, master = DIP 0.
• Parallel limit: up to 16 packs.

PC BMS (PACE PC200B)

• No Bluetooth on this BMS — monitoring runs through the dedicated WiFi port and the WIFI-RS232 module into Gobel VRM.
• Automatic DIP addressing, master = DIP 1 — the BMS numbers the slaves itself.
• Parallel limit: up to 63 packs.

Same on both: CAN / RS485 closed-loop communication with the inverter, 16S LiFePO4, and the 2A active balancer that keeps all 16 cells synchronised.

Pick JK if you want phone-side access without buying a module and your bank stays at 16 units or fewer. Pick PC if you are planning a large bank or want the addresses assigned automatically. Tell us your intended bank size and how you want to monitor, and we will confirm the variant before you order.

The pack communicates over closed-loop CAN or RS485 and is verified against 40+ inverter brands, including Deye, Victron Energy, Growatt, Solis, Luxpower, Schneider, SMA, Sol-Ark and GoodWe.

Commissioning in three steps:

1. On the inverter set the battery type to Lithium, then choose the protocol matching your BMS. For Deye with the PC200B, use DEYE330 over CAN (or DEYE over RS485).
2. Run the comms cable from the inverter to the master pack only. In a bank, slaves never talk to the inverter.
3. Confirm the master has recognised every pack in the bank before you close the DC breaker.

The RJ45 end of the comms cable is not standard Ethernet pinout — use the cable supplied with the battery, not a spare network lead.

Send us your inverter brand, model and firmware version before ordering and we will confirm the protocol and the cable pinout for your exact unit.

The limit comes from the BMS: up to 16 packs with JKBMS, up to 63 packs with PCBMS. Energy and current scale with the bank — every added pack adds its own 16kWh, and the bank's charge and discharge current is shared across the packs.

• Series connection is not supported on this model. Parallel only, so the bank always stays at 51.2V.
• Master setting: JK master = DIP 0, PC200B master = DIP 1. PC200B also assigns slave addresses automatically, so you do not number each slave by hand.
• One WiFi module is enough. In a parallel bank a single module on the master reports every pack to Gobel VRM.
• Before you connect: bring all packs to a similar state of charge and follow the cable and busbar order in the installation manual. Packs at very different voltages will trip protection on connection.

No — keep one BMS family per bank. A parallel bank is run by a single master BMS, and JK and PC use different parallel protocols and different DIP addressing, so a mixed bank cannot be addressed or coordinated as one system.

What can be combined safely:

• PC200 and PC200B (same PACE family) can run in one bank — set the PC200B as master and the PC200 as slave.
• Packs of the same BMS family, same voltage (16S 51.2V) and similar capacity and state of charge.

Firmware is not cross-compatible between PC200 and PC200B — never cross-flash them.

If you already own another brand and want to parallel it with this battery, send both battery models and both BMS models to [email protected] before connecting anything. Different BMS families may not coordinate charge limits or share current correctly, so we would rather check first than have you discover it under load.

Monitoring depends on the BMS fitted to your unit.

JK BMS

• Connect with the JK BMS app (Google Play or App Store) over Bluetooth — cell voltages, temperatures, MOS status and all protection thresholds.
• For cloud logging the pack reports to Gobel VRM when the JK BMS runs firmware V19; it is the only JK version that supports VRM, so check with us before changing firmware.
• The WiFi module for JK is WIFI-RS485.

PC BMS (PC200B)

• Plug the WIFI-RS232 module into the dedicated WiFi port and the pack appears on vrm.gobelpower.com — free, no subscription.
• In a parallel bank one module on the master covers every pack.

Both: data can also be forwarded to Home Assistant or ioBroker. The JK BMS download page hosts the Windows PC software and firmware only — the mobile app comes from the app stores.

Do not flash firmware to clear an alarm. Note the alarm code, and have the BMS log checked with us first; a flash will not fix a cell or wiring problem and may void the traceability of the pack.

This unit is stocked in our Europe warehouse, so it ships locally instead of from China.

• Delivery time: 7–15 days transit from dispatch. Pre-order units are dispatched once stock reaches the warehouse, so the shipping time shown on the page comes on top of this transit time.
• Destinations: EU countries only, plus Ukraine via Meest Post. We cannot ship EU-stock items to the UK or other non-EU destinations — order the China-warehouse listing for those (30–60 days transit).
• Duties: Europe-warehouse shipments are cleared DDP. The EU import duty rate for this product is 0% and nothing extra is collected at your door — the price you see is the price you pay.
• Handling: the unit weighs approx. 120kg and ships on a reinforced wooden pallet, so have a second person or a pallet truck ready at delivery.

Warranty follows the cell grade the pack is built with:

• High Grade (H) cells — 10-year warranty.
• Middle Grade (M) cells — 5-year warranty.

Both grades are brand-new, unused prismatic LiFePO4 cells with intact manufacturer QR codes, matched in-house by our CellFit matching on capacity, internal resistance and self-discharge. H cells are held to the tighter matching window and are typically manufactured within 3 months of dispatch; M cells within 6 months. Every pack ships with a Gobel Battery Passport recording the test data of each individual cell plus the full pack test report, traceable by QR code.

The PC-BMS version built with High Grade cells also carries IEC 62619 certification — ask us for the certificate of the exact configuration you are buying, since it is not issued for every combination.

Returns: accepted for quality issues, with a free return to the local warehouse within 30 days. Warranty claims, certificates and spare BMS boards: [email protected].
