1)
R
flashing is generally a user addressable fault / error
2)
R
charging status LED ON with heartbeat blink OFF
every 5 secs is a critical fault that generally requires service.

4.5 Push-Button Use in Non-Metered Version
The version of the ProStar MPPT without meter display fea-
tures a push-button that operates as follows depending on
the DIP Switch 1 setting:
Normal Mode (DIP 1 OFF)
• One quick press and release will clear any faults or
reminders that are present
• Press and hold for 5 seconds to initiate an Equalization
(EQ), if unit is set to manual EQ.
Lighting Control Mode (DIP 1 ON)
• A quick press and release will clear any faults or reminders
that are present. A second quick press will then conduct
a lighting test. If no faults or reminders are present, the
initial press will conduct a lighting test. A lighting test
is used to verify correct wiring in the load circuit and/or
verify the lighting components are operational.
• If no faults or reminders are active, press and hold for 5
seconds to initiate an Equalization (EQ) if the unit is set to
manual EQ.
Reset PS-MPPT to Factory Settings
To restore factory settings: Disconnect PV; disconnect
battery power; press and hold down the push-button;
re-start the PS-MPPT by connecting the battery; keep the
push-button depressed for 10 secs.
A Custom Edit Settings fault will occur. See p. 62 in Section
5 for details. The unit will then need to be re-powered to
resume normal opertation.
4.6 Alarms
Solar Overload
No LED indication. The ProStar MPPT will limit battery
current to the 25 or 40 amp maximum rating. An over-sized
solar array will not operate at peak power. The solar array
should be less than the ProStar MPPT nominal max. input
power rating for optimal performance. See Section 7.0 -
Technical Specifications for more information.
High Temperature Current Limit
The ProStar MPPT will limit the solar input current if the
heatsink temperature exceeds safe limits. Solar charge
current will be tapered back (to 0 amps if needed) to reduce
the heatsink temperature. The ProStar MPPT is designed
to operate at full rated current at the maximum ambient
temperature. This alarm indicates that there is insufficient
airflow and that the heatsink temperature is approaching
