Overview and construction

The Victron DC busbar 70 VDC / 250 A with 6 terminals and protective cover provides a low-resistance, high-current busbar for Victron and third-party DC systems.

This busbar features six M8 terminals (with M14 nuts) and a protective cover to prevent an accidental short circuit.

The busbar and hex nuts are made from tin-plated copper, while the terminals are stainless steel.

Both the base (UL 94 V-0) and protective cover (UL 94 V-0) are made from black, fire-resistant ABS plastic.

Application

The job of the Victron DC busbar 70 VDC / 250 A is to provide a common positive or negative connection for DC loads such as batteries, inverter/chargers or solar charge controllers in 48V systems.

Other devices like the Cerbo GX for example, can also be connected to this busbar.

Busbar installation considerations

Victron recommends connecting inverter/chargers and solar charge controllers in an alternating manner and using adjacent terminals. The reason is that this will reduce the distance the current has to flow through the busbar, lowering resistive losses.

For correct operation, it is essential that each inverter/charger or battery receives exactly the same voltage.

To ensure this, the DC path from the battery bank to each individual inverter and vice versa must be the same.

If there is a difference between the cable thickness or the cable length between the individual devices, there will be a difference between the voltages of these units.

To achieve a balanced system, please use matching cable types with identical cross-sections and lengths for each device from the battery bank or from the busbar.

The cable lugs should also be identical, with all connections tightened to the same torque values.

Carlo Gavazzi ET340 three-phase energy meter

The Carlo Gavazzi ET340 is a three-phase transducer, the device is suitable for active energy metering and for cost allocation in applications up to 65 A (with a direct connection), it supports dual tariff management. The ET340 is easy to use and install and quick to set up , thanks to the device’s self-power supply from the voltage reference inputs, automatic phase detection with wrong-phase-sequence warning and fast application-oriented programming procedure. It can measure imported and exported energy or be programmed to consider only the imported one. The ET340 supports RS485 Modbus and is compatible with Victron’s Venus OS - the operating system for GX devices, making it ideal for Victron based systems.
