Did you manage to find a ammeter that would measure up to 15A? Will your ammeter measure in and out?
I did. I went for
this one in the end. It has a bigger range than I need, but the seller assures me it'll read from -100A to +100A. It uses a shunt, which I'll place in the earth side of the circuit, so that it'll monitor the entire leisure circuit - sometimes positive, if I'm just charging, sometimes negative, if I'm just 'consuming'.
The seller was really helpful and quick to respond. I've also ordered
this one from him to monitor volts and amps from the panel. Both of these meters will require a separate power source, so I'm adding a 3xAA battery back and a push button, so the batteries will only be used when I'm reading the meters.
Even though I've ordered these digital meters I'm still really taken with the analogue meters from emy351 on ebay.
This one will measure -20A to +20A, and she has others coming in that will do -50A to +50A and -100A to +100A. Emy351 has been very helpful indeed, and although her analogue meters are more expensive than the Chinese digital meters, they do look nice and I may well go for them instead. I've wired the
solar panel such that the cable is joined using
Tamiya/
Kyosho connectors, so I can insert the meters quite simply. I'll probably see how well the digital meters work before either mounting them permanently or deciding to go for the analogue meters.
