Configurable battery protection kit
Everything on the DC side between batteries and inverter, already sized
Victron Lynx Distributor busbar · MEGA fuses · power cables · lugs
This kit is protection and wiring only: the inverter and the batteries you already have, or buy separately. Pick the inverter size and how many 48V batteries go in parallel, and the right material arrives: a fused distribution busbar, fuses of the correct rating, power cables in the cross-section the inverter requires, and lugs.
It suits any 48V low-voltage system — Deye, Pylontech, Dyness, V-TAC, BYD, Felicity, rack or tower batteries — as long as they sit in parallel on the same 48V bus.
What is inside
- Victron Lynx Distributor — distribution busbar with 4 fuse positions and a status LED on each one. One or two units depending on the configuration.
- Victron MEGA fuses 58V — one per battery and one per inverter cable pair.
- 1m power cables with lugs, in the cross-section your inverter size calls for.
- With a single battery on a single-input inverter no busbar is needed: the kit comes with an in-line fuse holder and a 250A MEGA fuse.
Why it matters: every hybrid inverter manual calls for over-current protection or a disconnect between battery and inverter. With two or more batteries, paralleling straight onto the terminals leaves each branch unprotected and the cable runs unequal, so the current shares out badly. A fused busbar fixes both, and the LED shows an open fuse at a glance.

The Lynx Distributor has four fuse positions. Once batteries plus inverter cable pairs go past four, a second unit is bolted to the first on the internal bars.
Picking the right size
Count the inverter's battery inputs, not just the kW: inverters up to roughly 12kW have one positive and one negative, while 14kW and above almost always have two and are wired with two cable pairs. The cross-sections below are the ones the manuals call for at that current.
↔ scroll the table sideways
| Inverter size | Typical battery current | Battery inputs | Cable cross-section |
|---|---|---|---|
| 5-6kW | up to 135A | 1 | 50mm² |
| 8kW | about 190A | 1 | 70mm² |
| 10kW | about 210A | 1 | 70mm² |
| 12kW | about 240A | 1 | 95mm² |
| 14-16kW | 260A to 300A | 2 | 2×50mm² |
| 18-20kW | 330A to 350A | 2 | 2×70mm² |
Two things to know: the cables from each battery to the busbar almost always ship with the battery itself, so they are not included; if you need them, just say so and we add them. This kit covers the DC side — the array combiner, the AC board and the earthing remain part of the wider design.
