Solid State Over-Voltage Disconnect
Operating Instructions
Please read these instructions before use
MIHV Series
The MIHV module provides an additional layer of independent Over-Voltage protection for Lithium based batteries.
To provide enhanced protection for both loads and lithium batteries the MIHV must be used with a suitable BMS. The
MIHV can also be used in Lead Acid based systems where a BMS is not used. The unit provides local and remote
system status indications.
Features:
● Automatic Over Voltage Disconnect to protect batteries and loads during a Over Voltage Event or BMS Tripping
● Auto-detection of 12V / 24V / 48V Nominal Battery Voltages.
● Self resetting Over Temperature Protection (OTP)
● 30% surge capability for short periods
● Remote Status Wire

Installation:
1)This equipment must be installed by qualied personnel only and incorrect wiring can cause re, injury or
death – GSL will accept no responsibility for MIHV misconnection or misuse.
2) Disconnect all live connections and ensure that all live terminals are in no danger of shorting.
3) Mount unit in a clean, dry area preferably to a grounded metal plane.
4) Make sure that the chassis of the MIHV is grounded. Not doing so is hazardous.
5) Connect BLACK wire to common negative MPPT and battery that you wish to protect.
6) Connect “OUT” brass terminal to the Positive terminal of the Battery and wait a few seconds for the GREEN LED to be SOLID
On.
7) Connect “IN” brass terminal to the output of the MPPT.
Notes: MPPT to be De-Energised during connection. The unit will only connect and reconnect following a battery detection.
Do Not connect loads to the unprotected IN terminal. Loads must only be connected to the protected
OUT Terminal.
Remote LED:
Connect the green wire to the Positive Side of a grounded LED.
LED Indication Guide
LED Indications and Alarms:
The chart to the left indicates the situations that the unit will indicate on the three LED
indicators. Those marked with a S or a A indicate that the LED is ashing.
“S” is for Symmetrical Flashing : • _ • _ •
“A” is for Asymmetrical Flashing : •• _ • _ ••
After each Alarm condition please perform the following tests:
Following No Battery Detected : Perform MPPT Test as described below, check
Battery BMS (Where Applicable), Check Battery and Fuses and Reset MIHV.
Following a Over Voltage Detection: Perform a MPPT Test as described below and
check Battery.
Following a Over Temperature or Low Battery: No need for immediate action, the
system may self recover. Check after a short period to see if alarm is cleared.
MPPT Test - Disconnect all loads and batteries, energize MPPT and check that input is
5V above the output. If not then MPPT may be faulty contact GSL for further information.
Reset MIHV- Disconnect MPPT and then Battery. Then follow steps 5-7 of “Installation”
