Could I ask what the relative merits are for installing an RS48/6000 and RS450/200 DC charging system for a domestic solar installation versus 4 individual Smart MPPTs. I have 43 x 470W panels and am trying to decide if extra €1400 is worth spending. The RS units work fine with long series panel strings(slightly easier to install). However I can mix parallel and series to work with a 150/70, 250/70 and 2 x 250/100TRs and that saves 1400. The advantages I see for lower cost option are price, ease to replace failed module, low start up voltage, ability to oversize a specific PV array on 1 mppt (as PV array is N face). What I am missing form my considerations is the 1400 of benefits that might come if I opt for installing the 2 RS units instead . Maybe you can help ..

I have the same issue when looking at these RS 450 units. Their input current limits being so low that you can't run any strings in parallel just cripples them to the point where the smaller cheaper MPPT boxes can in practise handle just as many panels at a much lower cost. I don't understand what the RS 450 is supposed to be for.

I am yet to see 5.7kw changing and i don't have any limits on charging
