MPPT FAQs
Q: What is an MPPT?
MPPT stands for Maximum Power Point Tracker and is a specialized converter designed to
maintain the PV voltage at the level in which it delivers maximum power to the load or battery.
The panel’s nominal output power can only be obtained with the use of an MPPT.
Q: What are the GSL MPPTs advantages compared to standard solar regulators?
1. Suitable for new lower cost high efficiency grid type panels since the GSL MPPT can
efficiently charge the batteries from relatively high voltage, say 12V batteries from 36V MPP
panels.
2. Less interference and more accurate voltages during absorption and float.
Q: What sorts of loads can I power with the MPPT30?
1.
The maximum bulk charge current with the MPPT30-1 on a 12V battery and 400W panel is
approximately 30A, so you can expect about 100AH per day which means a 100W load for
about 10 hours daily.
2.
Following the same reasoning with a 24V 800W panel the MPPT30-1 will supply a daily
load of 200W for about 10 hours.
3.
Following the same reasoning with a 48V 1600W panel the MPPT30-1 will supply a daily
load of 400W for about 10 hours.

Q: Is interference possible? and If so what do I do?
GSL’s MPPTs produce far less interference than conventional solar regulator during the
absorption and float stages, that is during most of its operating time, and its designed
to comply with local and international EMI standards however some interference is still
possible. If interference occurs first try and reorient the aerial or move the sensitive
equipment away from the MPPT wires. Ensure the MPPT chassis is grounded. Grounding a
battery terminal may also help and finally you can try adding ferrite clamps.
