The SRNE DC Battery Busbar Box, model SR-DCB-1, is an 800A DC distribution box for parallel battery and inverter connections. It gives installers a single, low-resistance point to combine multiple battery banks or feed multiple inverters from one source, instead of daisy-chaining connections at the battery terminals directly.
Rated for up to 60V DC systems — covering the 12V, 24V, and 48V battery banks common across SRNE’s inverter range — the SRNE DC Battery Busbar Box handles up to 40.96kW of total power through eight positive and eight negative wiring terminals.
What it does
When a solar or backup system outgrows a single battery bank or single inverter, wiring everything directly to the battery terminals gets unreliable fast — connections loosen, current distribution becomes uneven, and troubleshooting a fault means tracing wires back to a crowded terminal post. The SRNE DC Battery Busbar Box solves this by giving each battery pack and each inverter its own dedicated terminal on a shared bus, so current splits evenly and any single connection can be isolated without disturbing the rest.
This matters directly for the larger SRNE inverters already in this catalog: paralleling two or more units — the SRNE HYP4860S100-H, ASP48100S200-H, HESP48120S200-H, or HESP series three-phase models — calls for a clean way to tie multiple battery banks together and distribute that power across multiple inverters. The SR-DCB-1’s 800A rating comfortably covers that load.

Why installers use it
- Parallel batteries to increase capacity — combine multiple battery packs into one bus without overloading individual terminal posts
- Parallel inverters to increase system power — feed multiple inverters, such as paralleled SRNE HYP or ASP units, from a shared, evenly distributed source
- Reduce power line resistance — a dedicated busbar cuts resistance compared to chaining connections at a single battery post
- Even current distribution — each connected battery or inverter draws and contributes current more evenly than a daisy-chained setup
- Simplify expansion — adding another battery pack or inverter later means connecting to an open terminal rather than rewiring existing connections
Deployment scenarios in Kenya
Paralleled inverter installations Sites running two or more SRNE hybrid inverters in parallel — common with the HYP4860S100-H, ASP48100S200-H, or HESP series as load grows in stages — use the SR-DCB-1 to distribute battery power evenly across every unit.
Multi-battery-bank systems Larger Kenyan homes, SMEs, and commercial sites running several lithium or lead-acid battery packs in parallel use the busbar box to combine them into a single, low-resistance DC bus feeding the inverter setup.
Outdoor and semi-exposed installations The IP65 rating allows mounting in equipment enclosures or semi-sheltered outdoor locations, useful where indoor space near the battery bank is limited.
Frequently asked questions
What is the maximum current rating of the SRNE DC Battery Busbar Box? The SR-DCB-1 handles up to 800A DC and up to 40.96kW total power.
What battery voltage systems is the SRNE DC Battery Busbar Box compatible with? Any DC system up to 60V, which covers 12V, 24V, and 48V battery banks.
How many batteries or inverters can connect to one SR-DCB-1? Up to 8 positive and 8 negative connections, allowing multiple battery packs or inverters to share a single distribution point.
Can the SRNE DC Battery Busbar Box be installed outdoors? It carries an IP65 protection rating, suitable for outdoor or semi-exposed equipment enclosures, though installers should still follow standard practice for weather and dust protection on any DC wiring.
