24VDC HyPR 3000 Operator and Maintenance Manual
DC Interface
The DC Interface consists of an LED that reports the battery charging status (see Table 1 for a
functional description), an LCD screen and three (3) menu navigation buttons. System voltage and
net current are reported on the DC INTERFACE home screen.
There are some programmable settings that will be important to change or confirm, depending on
System configuration. A description of these settings and their locations in the menu map are shown
on subsequent pages.
Note:
the HyPR 3000 must be connected to an active PV array to access the
full functionality of the DC INTERFACE. Without PV input only the voltage and current readings on
the home screen are useful

Bulk Charge:
During Bulk mode, the charge controller can deliver full output to recharge the ESMs
rapidly and drive voltage up to the acceptance charge voltage setpoint. This stage typically takes the
battery to about three-quarters of full charge and at a rate that usually does not exceed 25% of the
battery’s amp hour capacity. This is also known as the “constant current phase”.
Acceptance Charge
: In this stage, the charge current gradually decreases as the batteries obtain
full charge. It is also known as the “constant voltage phase”. With the Li ESM 1300, the acceptance
charge phase is not necessary.
Float Charge
: This final stage compensates for the battery’s self-discharge and temperature.
Temperature and Power Output:
The HyPR 3000 charge controller can deliver full output in an
ambient temperature of up to 40 °C (104 °F). If an overtemperature condition exists, the charge
controller will cycle on/off, reducing average power delivery to within safe limits. During thermal
shutdown, the charge status indicator will display an OFF condition.

Solar Charging Status LED
The user interface charging status LED reports charging only via solar power input. The LED will not
illuminate when the HyPR 3000 is charging connected batteries using AC power. The information in
this section is relevant only when photovoltaic panels are part of the system.
