Hi all,

I came across this kit today, that monitors battery current and voltage, and includes lcd meters in with it, given the price of $30 australian, even with shipping it looked a good deal. I can't currently afford something like a smart guage and this looked like being a neater solution than a couple of cheap multimeters.

My set up will be 12 2v 110Ah cells in 2 parallel strings of 6, giving 220Ah @12v, with 2 85w solar panels. Does this look like a reasonable monitoring solution until I can afford a neater option.

Alternatively, I'm looking at a more complex charge controller than my current basic 10a unit such as this

which has similar options built it. I'd appreciate your opinions.

Cheers,

Justin.

For the price the kit looks ok.

Sounds a bit of a faf to set it up (shunt wire & adjusting the pots).

Also dont get why it uses two displays when it could cycle one?

It wont help you know when the bat is full as it can oly give volts & as the system will be under charge or load nearly all the time a plain V reading is not enough.

The smartguage does much more (and less as no amps) but is LOTS more money.
