@Chez nous it looks like a Smartsolar 100-50 is suitable for your 5 x 175w panels.

Dont forget to have a series fuse on both the positive and negative cable for each panel.

^ should 1 panel go faulty, the other 4 panels can dump their energy into it, smoke / fire.

@Chez nous gottya.

It kind of depends on what batteries you have, and are likely to up date to.

The Centaur is only for lead acid batteries due to the locked in temperature compensation.

The Skylla suits both LA and Li. Suitable for fully integrated Victron Gx controlled systems.

The Phoenix suits both La and Li. Requires a Mk3 adapter and computer to program.

The Phoenix IP43 suits both La and Li. Can be programmed / monitored with a phone / tablet. With Smart networking you can link the charger with your BMV712 to have accurate battery voltages / temperatures. If your mppt's are Smart, you can include them into the smart network
