Safety
●Do not use in a damp, dusty, or corrosive environment
●Do not cover air vents to ensure proper cooling
●Do not attempt to service the machine. Battery replacement and fault
diagnostics must be done by a qualified technician
●Be aware of the potential risk of high voltage inside the unit.
●Even if the system is disconnected from mains power it may still be live (230v).
●Never plug in appliances that exceed the MPSG power rating (eg. kettles, hair
dryers, vacuum cleaners, etc.)
●Some inductive load equipment- (motors, laser printers, etc.) have start-up
power requirements two to five times their normal capacity.
●Battery charging can be from AC mains or Solar power or a combination of
both. If charging via a generator the generator needs to be started and running
stable before connecting to the MPSG input ④.

Operating Instructions
●Use the supplied kettle cord to connect from an Eskom wall socket (230V) to the
AC INPUT ④ on the side of the machine (see side panel diagram icon ④
●Move the BATTERY SWITCH ① on the side of the machine up to the “ON”
position. The machine will come on and begin its set up.
●If AC power is not available from the Eskom socket, then the machine will not
automatically start up. In this case move the BATTERY SWITCH ① on the side of
the machine up to the “ON” position and press the red power button ⑫ until it
beeps. The machine will start up and function on battery power. Once AC power
returns the machine will stay on and recharge automatically.
●A multi plug and/or extension cable can be used to connect several devices to
the outlets ③ at the side of the machine. Ensure the total power requirement
for your devices/appliances does not exceed the MPSG rating. High powered
items like hair dryers, kettles, irons, microwaves, vacuum cleaners, etc. will cause
overload and could severely damage the CPU. Damage caused by excessive
overloading is not covered under the warranty.
●Once plugged in, turn on your devices/appliances in sequence, starting with the
biggest load first.
●The system will charge the battery automatically and power your appliances
using solar or mains electricity. When fully charged, the battery capacity display
shows five bars and maintains a float charge. (NB. the use of solar panels ⑤ is
optional.)
●If a power cut happens the machine immediately switches to battery power. 4
beeps warn the unit has switched to battery power. The default setting is for the
machine to then stay silent.
●An audible beeping warns when the battery is low. The machine will
automatically shut down soon after this. When AC power is restored the MPSG
will automatically start up and recharge the batteries. Draining the battery to the
point of shutting down, however, is not recommended. Always aim to recharge
before the battery is drained beyond 70% (and less if possible) for longer overall
battery life.
●The MPSG is not designed for connection to a DB board.
●The intelligent cooling fan ② will remain in QUIET MODE and will only increase
if the unit is in a hot environment and the internal temperature exceeds 45º C
●If the machine is not being used for a prolonged period disconnect AC ④ and
move the DC breaker ① on the side of the machine down to the “OFF” position
●Refrain from pressing the blue function button ⑬ unless you have read and
understood the function settings. Changing from the default setting 1 may lead
to unnecessary battery drain and decreased lifespan.

Function Settings
Keeping the function button pressed for more than 5 seconds will scroll through the 3
available settings. When the desired setting appears, release the button and the unit
will change to that setting. However, we strongly advise not changing from mode 1 or
2 for the reasons listed in section 3 below.

SET
MAINS PRIORITY MODE. This is the preferred mode, and we advise using this
setting in all circumstances. Under normal operation, power from the grid will
supply the load and, at the same time, maintain the battery charge. When there
is a power cut the MPSG will immediately switch to battery power providing high
quality, pure sine wave electricity to the AC outlets ③ and your connected
appliances. When power is restored, the battery will recharge. If a solar panel is
connected the unit will automatically use any available solar to charge the battery
and run appliances, even when AC power is available.

SET
MAINS MODE WITH BATTERY SAVING DURING POWER CUTS. Under normal
operation, power from the grid will supply the load and, at the same time,
maintain the battery charge. When there is a power cut the MPSG will
immediately switch to battery power providing high quality, pure sine wave
electricity to the AC outlets. If, during a power cut, no power is needed at the AC
outlets ③ e.g., no appliances are plugged in or are switched off, then the MPSG
will detect no power requirement and automatically switch the AC output to zero.
This state requires no power inversion and cuts battery energy consumption to its
lowest. Every 10 seconds the machine will pulse 230V to the AC outlet and if a
power requirement is detected then AC will resume and stay on for as long as
required. If, at any time, the load requirement drops to zero again, the AC will
turn off and resume pulsing every 10 seconds.

SET
BATTERY PRIORITY MODE. This mode should only be set if the user wants to
prioritize solar charging and not use any AC mains input. However, it is
recommended to always use MODE 1 - MAINS PRIORITY MODE, even if you have
solar connected because, in MODE 1, the MPSG will still use solar charging but
ensures the battery is not deeply drained in cloudy conditions or at night. It does
this by using AC to keep the battery topped up. Repeated, unnecessary draining
of the battery to very low levels in MODE 3 will reduce its overall lifespan. MODE
1 avoids this situation while still utilizing solar power to its maximum. The only
situation where MODE 3 would be useful is where the load requirement is
relatively small so that it only drains the battery by a small margin overnight and
has enough solar power during the day to completely recharge the battery before
the next overnight use.

The USB 5VDC ⑪ and 12VDC ⑩ Output sockets can be switched on independently
and used even when the main machine (AC output) and lcd screen are switched off.
●To use the 5VDC ⑪ and 12VDC ⑩ Output sockets when the main machine
and lcd screen are switched off make sure the battery switch ① at the side
is ON, illuminating the yellow DC Load light ⑧. The DC Output switch ⑨
on the front panel should also be switched ON.
●The DC Output switch ⑨ controls power to the DC outlets. Even when the
main machine and lcd screen are running, the DC outlets can be isolated and
switched ON and OFF using this switch ⑨.
●The two 5VDC ⑪ USB ports provide a maximum current of 1 amp each i.e.,
2 amps in total combined.
●The two 12VDC ⑩ ports provide a maximum current of 1 amp each i.e., 2
amps in total combined.
●Before connecting any electronics, confirm your DC load current does not
exceed the output rating of the DC port.
●Ensure the connecting plug type and polarity match the output port.
Reversed polarity or any short circuit can damage the equipment.

Solar Connection
The MPSG has a highly efficient MPPT solar controller. Connecting a solar panel
charges the battery and provides longer run times during power outages.
●Before connecting a solar panel, the On/Off DC Switch ① on the side of
the MPSG machine should be in the off position
●Ensure the correct panel voltage is used (determined by the voltage of your
MPSG machine). The solar panel open circuit voltage should be 1.5 to 1.7
times the MPSG rated voltage.
●The MPSG 500 is a 12v machine meaning a solar panel open circuit voltage
of 18 –20V is needed. Do not exceed 300W total power.
●The MPSG 1000 is a 24v machine meaning a solar panel open circuit voltage
of 36 –40v is needed. Do not exceed 600W total power.
●Use the right diameter wire based on panel output and distance from the
MPSG.
●Connect the panel to the Solar Input ⑤ + / - MC4 connectors. Make sure
to double check the correct polarity (solar panel positive output to MPSG
positive input and solar panel negative output to MPSG negative input).
Incorrect or reversed polarity may damage the solar controller.
●An in-line circuit breaker/fuse should be used between the solar panel and
MPSG to isolate incoming power from the panel to the machine. Once the
solar panel is connected to the machine the in-line circuit breaker can be
switched on. The On/Off DC Switch ① on the side panel of your MPSG can
then also be switched on. Reverse this procedure when disconnecting a
solar panel.
