3.Using MPS as Wind/Hydro Generator Charge Controller (Diversion Control)
This chapter describes the available features and how to set up and install your MPS as dumpload
switch for diversion control in stand-alone mode.
3.1 MPS Features:
Battery System Voltage Detection
MPS can be used in 12 V, 24 V, or 48 V battery systems. The nominal system voltage is detected
automatically when connected to the battery bank.
System Grounding:
MPS can control diversion loads in positive and negative grounded systems. Grounding is selected
by wiring of your MPS, see details in chapter 3.3.2.
Diversion Load Current:
MPS is available in two versions:
Overload and Short-Circuit Protection:
Diversion load will be reconnected automatically after one minute.
Overtemperature Protection:
To protect MPS from overheating and damage due to overtemperature, MPS will switch off
the diversion load. Overheating can happen if MPS's ventilation grill is blocked or ambient
temperature is too high.
High Voltage Protection (HVD):
To protect the diversion load from
high voltage, MPS will disconnect
the diversion load if battery
voltage is higher than HVD level.
Diversion Load Funcionality:
MPS can control a wind/hydro generator input, which always has to be directly connected to
the battery. This is done by switching a diversion load in parallel to the battery if the battery
