Victron battery shunt1/23/2024 ![]() All main distribution/service entrance panels such as Square D utilize UL489 branch circuit rated breakers. Most generators come with a UL489 branch circuit output breaker. The 3k and 5k VE Panels are supplied with 2 pole 60 Amp continuous duty rated breakers for the generator input, utility input and AC input/output bypass switch. Refer to the list of torque values in section 3.1. Installer connections are shown in Figure 30. These wires also connect to the VE Panel terminal busbars of the same name. AC1 in line and neutral, AC2 in line and neutral, and AC1 out line and neutral conductors are marked as such. ![]() The output of the inverter terminals are wired to the VE Panel AC output terminal busbars.Ĭorrectly sized conductors are prewired from the VE Panel breakers to connect to the inverter AC line and neutral input and output. The VE Panel comes wired with 6AWG wire for all AC circuits for the 3k and 5k versions. ![]() Use Figures in Section 4.3 to view the AC connection points inside the VE Panel enclosure. Refer to the torque requirements in section 3.1. Any other additional connection will contribute to additional voltage drops and may loosen during use.Īll wiring to the inverter/charger and battery terminals should be checked periodically for proper tightness. To ensure the maximum performance from the inverter/charger, all connections from the battery bank to the inverter/charger through the VE Panel enclosure should be minimized, the exception is the DC circuit breaker in the positive line and the DC shunt in the negative line. The battery bank voltage MUST match the DC voltage required by the inverter/charger (i.e., 24-volt battery bank for a 24-volt inverter/charger), or the inverter may be damaged. When the inverter/charger is installed in a Photovoltaic System, the NEC requires that the DC circuit conductors and overcurrent devices to the inverter/charger be sized to carry not less than 125% of the inverter/charger's maximum current rating.Ĭrimped and sealed copper compression lugs with a 3/8” hole should be used to connect the battery cables to the DC disconnect breaker and the DC shunt inside the VE Panel enclosure. Disconnect all power sources before removing the coverĮven though DC voltage is “low voltage”, significant hazards may be present, particularly from short circuits of the battery system.īefore wiring the DC cables, review the safety information at the beginning of this manual and the following information to ensure a safe and long-lived system.įailure to use the proper terminal may cause the connection to heat-up, and may eventually fail or become a fire hazard.ĭO NOT connect the battery cables to the inverter/charger until all wiring is complete and the correct DC voltage and polarity have been verified. Connections required by installerĭuring normal operation, the terminals, busbars, and electrical components inside the VE Panel enclosure may be energized – DO NOT TOUCH.
