Installation
Long-distance wire runs
If there is a significant distance between the PV array and the controller and/or the controller and the battery, larger wires can be used to reduce the voltage drop and improve performance. Refer to Table
To use a larger size wire, use a splicer block (terminal block) intended for this purpose. This allows the larger cable size from the batteries to be “spliced” to the smaller wire size connected to the controller.
Follow manufactures recommendations for torque and mounting (if required). Splicer blocks and
Maximum One-way Distance and Wire Size
Important: NEC Article 690 and local electrical codes should be consulted for wire sizing and any additional installation requirements.
•For a C60 use a 60 amp, 100% Continuous Duty breaker and #6 AWG, 90 °C wire.
•Larger wire sizes may be used to improve performance, but are NOT approved by UL to be installed in the controller. Use a splicer block as previously described.
