Two MPPT 250/60 in parallel. Do I have to adjust the individual current?

Hi Community,

nowadays I am running one MPPT 250/60 with one MP II 3000 and two Pylontch 2000c batteries. The MPPT current setting is at 50 Amps.

Question: When I add another MPPT 250/60, do I have to set the max load current to 25 A on per MPPT? In order not to over charge the battery pack with more than 50 Amps?


Thanks for your advice.

If the pylons are setup correctly with dvcc they will control the chargers, no need to manually limit them.

If you set the current at 25A the MPPT will put out only 25.So what is the point of limiting its power ?Instead of having 1 MPPT pushing 60 amps you want to put another one and limit both at 25 ? Also if US2000C BMS works in the same way as the US3000C,when it detects higher currents than what the battery can take it will turn off your MPPT.
