Lex,
Yes the Steca regulator is PWM controlled !!
Steca PWM technical specs the Steca regulator does not even get warm.
You can't seriously believe the Steca reg is simply wasting 7.1 Amps "heating up the shunt in the regulator" on any *permanent* basis, that just does not happen.
UNLESS-> your suggesting it's being "regulated" by the Steca regulator so it will not send the full 12 Amps to an already fully charged battery system, with-out actually using the word "regulate" ??
consider this:
will a Toyota 100 Amp Alternator, at ALL times, supply the full 100 Amps to the battery ?
or
will a Ctek 50 Amp battery charger, at ALL times, supply the full 50 Amps to the battery ?
-> of course not
reason being the 100 (or 50) Amps is "regulated" by the appropriate device
exactly the same as Steca Solar regulator "regulates"
Solar power to the battery.
The picture posted above clearly shows what's happening:
Solar system delivering 12 Amps to the Solar regulator
Solar regulator sending just 5 Amps to *TRICKLE CHARGE* the 14.3 Volt battery system
Easy to see and understand, no tricks, no gimmicks and no problems
This picture (below) clearly show 10 'Plus' (cause it can't show 12) Amps is charging the battery system, however with the 7 Amps you claimed to be "wasted" heating up the shunt, takes the total to 17+ Amps minimum, from a 200 Watt solar system - I believe this
pic shows your numbers & ideas don't add up to a credible explanation as I'm sure you will also agree, it's impossible to get 17+ Amps from a 12v, 200 watt Solar system.
