Battery Connection & Charging Requirements
6. BATTERY CONNECTION AND CHARGING
REQUIREMENTS
There is a DC (Battery) circuit breaker in the distribution box. Before
connecting the batteries, please have the battery specifications on hand.
Note on DC Wiring and NEC
The maximum EverVolt Battery DC charging current is 60A for DC
Coupled and 100A AC Coupled systems. Under fault circumstances, a
flashing error 06 will show on the inverter display. See fault table in this
manual.
Some electricians or installers may be unfamiliar with DC wiring in a
residential setting. Make note of all relevant codes, which may include:
1. NEC 690.31(G) for DC PV circuits in buildings.
2. NEC 215.12(C)(2) for correct DC wiring coloring.
3. NEC TABLE 310.15(B)(16) for Allowable Ampacities of Insulated
Conductors for Not More Than Three Current-Carrying Conductors in
Raceway (conduit wiring over 12").
4. NEC TABLE 310.15(B)(17) for Allowable Ampacities of Insulated
Conductors in Free Air (chassis wiring).
WARNING: To maximize battery capacity, it is important to keep
the voltage drop from the 150A current as low as possible.
