22. Failure to use the proper terminal may cause the connection to heat up and may eventually fail or become a fire hazard CAUTION DO NOT connect the battery cables to the inverter until all wiring is complete and the correct DC voltage and polarity have been verified gt When inverter is installed a Photovoltaic System the NEC requires that the DC circuit conductors and overcurrent devices to the inverter be sized to carry not less than 125 of the inverter s maximum current rating e The DC positive and negative cables from the battery bank should be tied together with wire ties or electrical tape approximately every six inches This helps improve the surge capability and reduces the effects of inductance which improves the inverter waveform and reduces the wear of the inverter s filter capacitors e Crimped 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 MMP enclosure e The battery bank voltage MUST match the DC voltage required by the inverter i e 24 volt battery bank for a 24 volt inverter or the inverter may be damaged e DC cables must be of a type listed for use in conduit RHW or THW e To ensure the maximum performance from the inverter all connections from the battery bank to the inverter through the MMP enclosure should be minimized the exception is the DC circuit breaker in the posi
