Electrical meters and DC

[femail]

Lol Ok i need more data!

Yes only seven fit on the roof. Sw facing. Estimate of 40 degrees.
I'll look at the wiring and see if I can establish its mode of connection.

I'll ring along my drill driver and open the box to work out what the battery is.

If I can get an AC pump to work thats the ideal option from the metering perspective (even if I need to pop a rectifier in to convert to DC at the pump) But this raises the problem of getting a pump to work given the inverter rating. The DC pump is I suppose 3 phase equivalent.

Anyway I'll be able to get you new data next Friday.

Wot Worcester said!

You need many many more batteries to make anything of that solar array....my boat has 6 12v batteries (675 Ah) supplied by 500 watts of solar (2 panels) and I've room for expansion on a charge controller comparable to the pair you have! To make the most of your system (assuming around 200 w/panel or so) I would think 800-1000 Ah (at 24v) would be about right. That would look like about a pallet full.

Back to your original problem though....I'm confused by your subsidy....and hence your metering. Normally, a shunt would be placed in the negative battery cable, this is then hooked up to a meter to tell you what the battery state of charge is. They often have an amp hour counter, which is at best, an estimate of what has gone in and out. They need zeroing out regularly to remain synchronised and can, in the wrong hands be far more trouble than they are worth! Your Elster sounds like it does something totally different.

The elster is a generation meter, of which the op recieves FIT payments for generating electricity from the solar panels for a off grid system.

Hope this helps

As Earthstore said, it is for measuring the generated 230V 50Hz AC (i.e like you would an off grid house) - CAB Marine, as you live on a boat, then unfortunatley even if you did something similar then you would not be eligible for the generation tariff.
