Mounting and Connecting
MPS is intended for indoor use only. Protect it from direct sunlight and place it in a dry environment.
Never install it in rooms with elevated humidity (bathrooms, etc.).
The controller warms up during operation and should therefore be installed on a non flammable
surface only.
There are 3 different possible applications for using the MPS as stand-alone unit:
Using MPS as a DC load switch for deep discharge protection (Chapter 1, page 21)
Using MPS as a photovoltaic charge controller (Chapter 2, page 26 )
Using MPS as a wind-/hydro generator charge controller (diversion control) (Chapter 3, page 31)
1. Using MPS as a DC load switch with deep-discharge protection
This chapter describes how to set up and install your MPS as stand-alone DC load switch with deep-
discharge protection and the available features when performing this duty.
As a stand alone unit, MPS provides you five voltage thresholds (LVD1 to LVD5) for disconnecting DC
loads when battery state of charge becomes low.
Several independent MPS units can also operate in the same system, providing up to the nominal
current of each individual MPS unit to several different loads.
Do not use multiple MPS units in parallel in to provide higher current to a single load in stand-alone
systems without the use of optional accessory MCU. This is only possible by using MPS together with
MCU (not object of this manual).
1.1 MPS features:
Battery system voltage detection
MPS can be used in 12/24/48V battery systems. The nominal system voltage is detected automatically
when connected to the battery bank.
System grounding:
MPS can control loads in positive and negative grounded systems. Grounding is selected by wiring
of your MPS, see details in chapter 1.3.2.
Load current:
MPS is available in two versions:
Nominal load current
Overload and short circuit protection:
MPS' advanced overload protection allows overload for a limited time, to enable inrush current when
switching on loads:
Load current in % of nominal current:
Type
110% to 150%
150% to 200%
