5Installation Manual
INTRODUCTION (DC-Coupled)
The EverVolt provides power to the essential loads by utilizing power
from PV panels, the utility and batteries. When the PV panels (two string
input) generate enough power, the inverter can support the essential
loads, charge the batteries and feed back to the grid all at the same time.
When the energy generated by the PV panels is not sufficient to support
the essential loads, the inverter takes power from either the batteries or
the utility depending on the mode the homeowner has selected.
To accommodate various power situations, the EverVolt is designed to
handle continuous power from PV panels, batteries and the utility. When
the MPPT input voltage from the PV panels is within the acceptable
range, between 250 and 430VDC, the inverter is able to feed the grid
and charge the batteries. The EverVolt inverter is compatible with
monocrystalline, polycrystalline and Panasonic HIT PV panels.
Note:
∙ Positively grounded PV modules are not compatible with the
DC-coupled EverVolt system.
∙ When PV input voltage is lower than 250V, the power of the
inverter will de-rate.
