MPPT12-1 General Information:

 This MPPT is designed to auto detect 12V and 24V battery systems and select a suitable 

  charge regime.

  or 24V batteries respectively.

 The absorption phase is entered following a low battery condition and is maintained for 

  approx. 1.5 hours.

.

 This MPPT has a built in multilevel over temperature protection to improve product reliability  

  while maximising output power availability. 

 The peak maximum output power is 250W and the continuous output power is 150W on 12V 

   systems and 200W on 24V.

  over 20%. 

 The fuse PVF can be replaced by a suitably heatsinked 20A 60V schottky diode ( its anode 

  connected to the + panel and cathode to the MPPT white wire). This diode will avoid a small 
  drain during night time (approx. 0.04A ) as well as protect against panel short but it will also 
  slightly decrease the battery charge current.

Note: 

First start up may take up to one minute.
