Good evening another question if you would be so kind: )
I have just taken delivery of two TRIRON 4210N charge controllers.
We intended to feed them each with two 340w panels in series.
The online advert said : -
EPEVER 40A 12/24V TRIRON Maximum Power Point Tracking Solar Charge Controller
The controller has an input voltage up to 100V enabling the unit to work with both On and Off Grid Solar panels. and a maximum input of 780 Watts for 12v batteries and with 24v batteries 1560 watts
The sticker on the top of the two 40 watt units we received says :-
Max of PV INPUT POWER 520 WATTS 12 VOLT 1040 W at 24 VOLTS.
We ordered the units on the basis of two panels at 340 watts in series = 680 watts.
However I read in the instruction book :-
Rated Charge Power 520w/12v 1040w24volts
Max PV Array 780w/12v 1560w/24v
The 340w panels will be in series the 12 volt batteries are in parallel as the inverter is 12 volt.
It is a bit confusing or misleading perhaps.
As I see it the TRIRON 4210N 40A charge controller will except the 680 w from the panels OK but can only produce 520w at its output ?
The lable on the unit appears a contradiction though please see image as it says 520w max PV input power ?
I have messaged the seller but they are closed till tomorrow.
Thank you for your time God Bless Chadd

Just had a reply I have to say they are very prompt : )
Hello Allen
The maximum solar power (Watts) which can be connected to the 40A controller is 780 Watts
The maximum input power to the batteries is 520W
The above is for 12V batteries. And double for 24V.
The difference between the two figure enables higher rated solar panels to be connected to still achieve up to 520 Watts of battery charging power taking into account for example weather conditions which does substantially lower solar output.

Hallo Jeff,
Thank you for your reply.
I think the advert should have stated that fact,
I realise it does say input but a bit like purchasing a 100 MPH battery in a car and finding out it can only do 75 mph with it: )
I realise that the panels are unlikely to produce the maximum power, but just the same unless the buyer is familiar with all these ratings, he could as we have, not get quite what he expected..
