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 MPPT’s advantages compared to standard solar regulators?

  

1.

 Suitable for lower cost non battery type PV since the MPPT can efficiently charge the 

batteries from relatively high voltage, say 24V batteries from 40V MPP panels.

2.

 Less interference and more accurate voltages during absorption and float.

Q: What sorts of loads can I power with the MPPT30HV?

1.

The maximum bulk charge current with the MPPT30HV 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 MPPT30HV will supply a daily 

    load of 200W for about 10 hours.

3.

 Following the same reasoning with a 48V 1600W panel the MPPT30HV will supply a daily 

    load of 400W for about 10 hours.

Q: Why are MPPT not more common in standalone solar systems?

Until now and despite their overwhelming advantages MPPTs have not been commonly used 

in standalone solar systems because of cost. The new GSL MPPT specifically addresses this 

issue making economic sense in a wide range of solar systems. 

Q: What sort of batteries should I use?

1.

 A deep cycle battery is a must due to the cyclical nature of the solar system with a 

   recommended battery capacity of at least a few days of running your load. 

2.

 A larger battery will not only give longer run time during low light but also will be able to 

avoid available PV power being unstored such as when battery reaches the float stage.

Q: How do PV temperatures affects charge current?

Temperature increase brings down the PVs maximum power point voltage reducing the 

MPPTs current gain available. In principle at 25C it is possible to achieve 30% gain but at 

40C, a more realistic average temperature, about 20% is still available.

 

Q: What happens at low PV currents?

The MPPT will outperform the conventional regulator above 3% of nominal panel power. 

Below 3%, about 10W in a 400W panel, the MPPT will have a slightly lower output current 

than a non MPPT.
