Your Battery Finally Talks to Your Monitor
One of the most frustrating things in an off-grid build is assembling components that refuse to communicate. You have a Victron monitoring system sitting there blind while your battery runs silent. This 78-inch comms cable eliminates that gap for Epoch Pro Series batteries. At Off Grid Vault, we believe every component in your system should speak to every other component — that is why we vet compatibility before anything ships. This cable connects your Pro Series 12V 120Ah or 300Ah battery directly to your Victron setup, delivering the real-time state of charge data you need to manage your power with confidence.
78 Inches of Install Flexibility
Battery compartments are rarely laid out perfectly. This cable gives you 78 inches of length to route from your Epoch Pro Series battery to your Victron device without strain or tight bends. Whether your battery bank sits below your inverter rack or beside your distribution panel, the reach accommodates most off-grid cabinet layouts. It is purpose-built for the Pro Series 12V 120Ah (DP12120H) and 12V 300Ah (DP12300H) models — not a generic cable you hope fits. You plug it in and your Victron system immediately starts reading accurate state of charge and health data from your battery bank.
No Guesswork on Compatibility
This cable is engineered exclusively for Epoch Pro Series batteries. It works with the 12V 120Ah (DP12120H) and 12V 300Ah (DP12300H) — and nothing else. That specificity matters because using the wrong cable can cause communication errors, inaccurate readings, or no connection at all. When you are monitoring your off-grid system through Victron, you need data you can trust. Off Grid Vault carries only components that are field-tested for the exact applications we list them for. If we say this cable works with your Pro Series battery and Victron monitor, that is because we verified it — not because we guessed.

★★★★★
“I had my Victron Cerbo sitting there with no battery data because I was missing this cable. Plugged it into my DP12300H and immediately saw state of charge, voltage, and temperature in the Victron app. The 78-inch length was perfect for my battery cabinet. Small part, but it completes the communication loop.”
Frequently Asked Questions
No. This cable is designed exclusively for Epoch Pro Series batteries: the 12V 120Ah (DP12120H) and 12V 300Ah (DP12300H). It will not work with standard Epoch batteries or other brands. Using an incompatible cable can cause communication errors or no connection at all. If you are unsure which Epoch model you have, check the label on your battery for the model number before ordering.
This cable enables communication between your Epoch Pro Series battery and Victron monitoring equipment. The specific Victron device compatibility depends on your system configuration — such as a Victron Cerbo GX, BMV, or similar monitoring hub. Since this is a Pro Series-specific cable, confirm that your Victron device supports the communication protocol used by Epoch Pro Series batteries. Our free system design consultation can help verify your setup.
Seventy-eight inches covers most typical battery compartment layouts where the battery bank and Victron monitoring device are housed in the same cabinet or adjacent enclosure. If your battery and monitor are separated by a longer run — for example, in different rooms — you may need an extension. Measure your actual routing distance before purchasing to confirm this cable length works for your specific installation.
Generic cables often have incorrect pin configurations or wiring that does not match the Pro Series communication protocol. That can produce inaccurate state of charge readings, intermittent connections, or no data at all. This cable is purpose-built for the DP12120H and DP12300H batteries to ensure reliable communication with your Victron system. Off Grid Vault only carries components that are field-tested for the exact applications we list them for.
If you are using a Victron monitoring system and want your Epoch Pro Series battery to report state of charge, health, and status data directly to that system, then yes — this cable is required. Without it, your Victron device operates without battery-level data from your Epoch battery. If you are using a different monitoring setup that does not involve Victron, this cable is not necessary.
Off Grid Vault offers a 30-day performance guarantee on all products. If this cable does not perform as specified with your compatible Pro Series battery and Victron equipment, you can return it uninstalled and in original packaging for a full refund. We are an authorized dealer and stand behind every component we sell. If you need help confirming compatibility before ordering, reach out for our free system design consultation.
