Unit 2, 110 Station Road, Seven Hills ,NSW,  2147, Australia

Model:

MPPT30-2

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 180AH. 

   

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 sorts of loads can I power with the MPPT30?

   

1. 

The maximum bulk charge current with the MPPT30 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 will supply a daily load of 

      200W for about 10 hours.

 

  3.

 Following the same reasoning with a 48V 1600W panel the MPPT30 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.
