Battery Cable Wiring for PV Systems
NEC rules state that battery cables cannot be of arc welding wire or other unapproved types: only standard building-grade wires may be installed. CEC allows for all types to be used.
Please check our NEEC Section for further reference.
Battery Voltage Regulation for PV Systems
Battery Wiring
Wiring batteries in series can up the voltage while a parallel connection can increase the capacity. Battery manufacturers offer a range of voltages and capacity ratings that will meet most requirements. The considerations that are most important in any installation include capacity in amp-hours (Ah), distance from the inverter and voltage. Choosing a battery configuration depends on your required power load and the expected time of operation during blackouts.
Generators & Energy Meters
North American generators come in either 120/240V split phase or strictly 120V output configurations. A 120V renewable energy system with a prewired 120V generator will simplify installation as a 240V generator will with 240V systems.
