Can I use a MPPT 100/50 to control 2 x 460E PV in parallel. Vmpp 42.77V; Impp 10.75A; Box 50.43V; Isc 11.28A
From the PV calculator online, it doesn't suggest to use the 100/50. From the excel sheet, it showed accepted PV however, with max.current min and max temp. This I understand, but it also has an attention note: More than 30% oversized PV generator. What does that mean. Can I use this 100/50 MPPT to control my 2 460W PV?
Hi @SV.SMEDjj
That will work fine, but..
You must be charging 12V, and the calculator is warning you that it will top out at ~700W, not the 920W you might be expecting. The 50A capacity relates to battery V, no relation to panel V.
"Box" 50.43V is supposed to be VOC 50.43V?
The battery will be 12V (nominal)?
If yes, you will not be able to use the entire power your 920Wp array can produce in good weather (the current to the battery and/or loads is maximum 50A, so for a 12V system, that's about 600W). But during cloudy days, when the PV generated power drops to 10% or even less, you will be glad that the PV array is slightly oversized.
