Solar Panels Solar Batteries , re charging.

[Gandalf69]

I have recently had panels fitted and very pleased with the results and am thinking about adding a battery to the system. As regarding re charging, is it a simple calculation? If, for instance, you have a system generating 5kwh at peak, will it recharge a fully drained 5kwh in one hour ( providing nothing being drawn off ) or is it more complex than that?

The charging and discharging of the battery is a function of its charger. You will be limited in both directions by this. Advise scoping the system you have in mind and checking charger specs

The battery I have in mind is a Huawai Luna 5Kwh. Am I right in thinking that the charging is managed by the Battery Management System?

Dunno about that model but the principle is that the battery needs to be charged and then to get useful power out, it needs an inverter to produce 240V. Some are totally standalone, which is where i guess you are, some systems can be connected to the Solar Invertor and use the Solar invertor to charge the battery and then the solar invertor uses the battery to produce the 240V and i suppose some systems, like, the Luna, are modular.

I would make no assumptions and speak to the manufacturer to make sure i have all the necessary bits.
