"PRM330"
OVERVIEW
The PRM330
solar
charge regulator can charge lead
(liquid, gel and AGM) and lithium 12V batteries
automatically c
ontrolling
supplied by the connected photovoltaic modules.
It
features
a MPPT (Maximum Power Point Tracker)
system that allows picking in every situation of the
maximum power supplied by the photovoltaic
module.
3 phase automatic charging system
Phase 1:
Bulk -
battery charging with maximum
current until the end-

Note:
the end-

Phase 2:

The position of the selector must be set according
to the
most suitable charg

The PRM330 is suitable for operation with 32 to 72-
cell photovoltaic modules up to a maximum power of
330W.
For optimal performance, you are advised to connect
the photovoltaic modules with a number of cells over
36, independent of the type of installation chosen (see
the "CONNECTIONS" paragraph).
