What a good idea. Simple and effective. Will tuck this away in my "could be useful one day' memory bankActually my Sargent unit (EC225) charger packed up a few years ago so I disabled the charger and now use the red switch to power up a 240v to variable DC output unit. The voltage output is matched to the output of the solar panels and feeds directly into the MPPT solar controller and this then charges the battery bank. So in other words the controller thinks it is sunny but in fact it’s being fed by DC voltage from the transformer. This has worked now for over 5 years. I do have a diode on the DC +ve of the transformer to prevent feedback from the solar +ve.
