Question 1

75/15 model: can i connect 2 120w panels assuming the max amperage is below the 15a?

Accepted Answer

IF you connect these in series, you'll get something like 36V max but around 6-7 A. Charging a battery at 14.5V with 240W would require 16.6 A. The MPPT will knock down the voltage to 14.5 and increase the current to 16.6A. I think it would work ok. If you connect in parallel, you'll get around 18V max and close to 15A which would probably be too close to the liit of solar input for the charge controller and you'd lose some potential power. This is hard to answer without seeing the specs for your panels, this is a guess.

Question 2

wii it work with a lithium ion battery? Specifically Tesla 263133603034

Accepted Answer

I am using this unit with lithium sulphur batteries and it is working out well. There are setting for different battery types. Think there is only one lithium battery choice.

Question 3

Hi there, i am hoping i didn’t mess up by assuming i could use this for a small parallel-series setup, bringing two 24v 7a 460w to charge two agm’s???

Accepted Answer

Only if you are 100% sure that 7A is what you get from the single solar panel. When you link them in parallel you'll be getting 14A witch is just under the maximum for the this unit. Just as a reminder the 2 ratings you want to keep an eye on are the Voc (volts) and Isc (amps) on your solar panels. If you are staying under those 15A limits then you could also consider the 75/15 model which is slightly cheaper. On paper it looks as if it would be too small but if you stay within the 75V and 15A maximums it will function just fine. It will not be able to utilize its MPPT functions fully, but it can still fulfill the task of charging 2 batteries if you are on a budget.

Question 4

can i use this contoller in a  12v system  with a 204 watt panel  and 33 v

Accepted Answer

According to the manual, the 100/15 Charge Controller can take 220 watts and 75 volts max on a 12v system.  Read up here, because solar panels become more efficient when it is colder, and you could go over the limit:  https://www.victronenergy.com/upload/documents/Manual-BlueSolar-charge-controller-MPPT-75-10-75-15--100-15-EN-NL-FR-DE-ES-SE-ul.pdf
