Got myself a 50amp charger coming. Bells and whistles. 7 stage. Will hard wire it to rcd protected 240 shore supply.

Best way to hook her up??

At the moment the 4 yo 4 x Trojan 105s (470 amp hr) are and have only been charged by the 270 watt solar array via a Mark PV Solar regulator and the Balmar 100 Amp alternator.

Most of the boat electrics is run on 12v supply. I need the charger in particular to supply juice for the deiso heater through winter whilst at berth. The solar array seems to take care of the 12v frigomatic and lighting ok so far.

The electrics are hooked up to a link 2000 battery system which seems to show the voltage correctly and the amps used look legit although they door go into the positive when the sun is out and all 12v usage has ceased. The hours used/remaining are way out and I'm guessing need calibrating.

She also runs through the Mark PV Solar regulator which seems to show ok LED representation of battery capacity but other info such as amps coming in look off.

I'm wondering if I just hook the charger up to the terminals direct or should I run the solar array feed and the charger feed to a switch so that one or the other is feeding the battery only? ??
It's a ****ing mess in the battery box atm and the less I stuff with it the better until I can afford down time.

Thoughts????
