Stop Guessing at Component Compatibility
When you piece together an off-grid system from different vendors, the biggest risk is not a bad battery — it is a communication failure between components that should be talking to each other. This cable eliminates that risk for Epoch Pro Series owners. At Off Grid Vault, every component we carry is pre-vetted to work together, and this 78-inch cable is the verified link between your Epoch Pro Series 12V 120Ah or 300Ah battery and your Victron monitoring stack. No adapters, no firmware mismatches, no hoping it works. Plug it in and your battery health data flows where it belongs.
See Your Battery State in Real Time
Off-grid systems demand visibility. You need to know your state-of-charge, cell balance, and overall battery health without opening a compartment and guessing. This cable delivers that data straight from your Epoch Pro Series battery to your Victron monitoring equipment — the same interface trusted across serious off-grid installations. At 78 inches, it gives you enough slack for practical battery placement without signal degradation. Whether you are monitoring a 12V 120Ah setup in a cabin or a 12V 300Ah bank on a homestead, the data feed is clean, consistent, and immediate.
Built for One Purpose, Done Right
This is not a generic cable pulled from a parts bin. It is purpose-built for the communication protocol used by Epoch Pro Series batteries and Victron equipment. That specificity matters — the wrong cable means no data, no monitoring, and a battery bank you are flying blind on. By restricting compatibility to the 12V 120Ah (DP12120H) and 12V 300Ah (DP12300H) models, Epoch ensured this cable handles the exact signal requirements without compromise. Off Grid Vault carries it because it matches the standard we hold for every accessory: it does exactly what it is supposed to do, with no ambiguity.

★★★★★
“I ordered this cable alongside two Epoch Pro Series 300Ah batteries and a Victron Cerbo. Plugged it in, fired up the Cerbo, and had full state-of-charge data within seconds. No configuration headaches, no firmware fighting. Just clean battery telemetry on the screen. If you are running this combo, do not skip this cable — it is the piece that actually makes the monitoring work.”
Frequently Asked Questions
No. This cable is designed specifically for the Epoch Pro Series lineup — the 12V 120Ah (DP12120H) and 12V 300Ah (DP12300H) models. The communication protocol differs between battery series, so using this cable with a non-Pro Series battery will not establish a data connection to your Victron equipment. If you are unsure which Epoch battery you have, check the model number on the battery label before ordering.
This cable is designed to link your Epoch Pro Series battery to Victron monitoring devices that accept the battery's communication protocol. The exact Victron unit compatibility depends on your monitoring setup — check your Victron device's supported battery list to confirm it accepts Epoch Pro Series communication. Off Grid Vault's free system design consultation can help you verify compatibility before you buy if you are building a new setup.
This cable is a small component, but in an off-grid system, every connection matters. When you buy from Off Grid Vault, you get an authorized dealer that stands behind what it sells. If the cable does not perform as specified, our 30-day performance guarantee covers it. You also get access to our system design team — if you are unsure about compatibility, we will help you confirm it before the cable ships. No ticket queues, no guessing, no support that disappears after the order.
That depends on your battery-to-monitor distance, but 78 inches covers the majority of typical battery cabinet and compartment layouts. If your Victron monitoring device is mounted more than 78 inches from your Epoch Pro Series battery, you may need an extension. We recommend measuring your actual run before ordering. If you need help planning cable routing in your system, our free system design consultation includes guidance on component placement and cable management.
The value is not in the wire — it is in the guaranteed compatibility. A generic cable that costs less but does not carry the correct communication protocol means you get zero data from your battery to your Victron monitor. You saved a few dollars and gained a blind spot in your off-grid system. This cable is purpose-built for the exact signal requirements of Epoch Pro Series batteries. It works the first time, every time. That is worth the price.
This cable is built for the communication protocol between Epoch Pro Series batteries and Victron equipment. It is not designed for use with other monitoring brands or systems. If you are running a different monitoring platform, check with that manufacturer for the correct comms cable for your battery model. Using an incompatible cable will not damage your battery, but it will not transmit data either.
