Hi not sure if Magnum are available in France. I use a Magnum inverter charger on 48 volts. These are around $2000 here in the states. It makes a true sign wave and and can put out 240volts at 83 amps They are fully programable for every type of battery, ideal for the Agm and every situation. Just program it from the manufactures specs, also has a battery temp sensor. I believe the maximum charging is 60 amps thou. I only charge at 30 amps. It has a searching mode, if nothing is on it makes the inverter go to sleep saving big time on batteries. With an amp shunt you can see how many amps you have taken off of the batteries and how many amps you have put back in, add 10 percent more for losses. This unit charges batteries and inverts all the same time, it monitors the electric going to your house. Your program tells the charger when to cut back on charging and give more power to the house. It has 4 stages of charging, 1 being a equalizer or a desulsifier.
With batteries it not good to take of more than 20% of a full charge, this hurts a battery taking some of the life out of the battery.
48 volts is the best way for the dc amps to ac amps loss.
My wife and I love the Magnum inverter/charger, and as you can see highly recommend it.
