This meter is a perfect example of why Solar Bob says an MPPT controller is not needed on small systems. Cheapest I could find this 15 amp controller was $195 add another $40 to $50 for the remote meter. Yes it might get 10% more from your 200 watt panels. But for the same $$ or less you can buy a 3rd 100w panel and a 30 amp MWP controller, at 30% increase.bsharp007 said:You could go with this, it's a MPPT controler that is rated to 200 watts according to it's specs.
It simply plugs right into the same spot and wires where your other Sunsaver is. It also has a jack where you can plug in their version of a volt meter which they call a remote meter. That's what I did, very easy install. I'll add another 90 watt panel to the roof soon. There's pretty good deal on ebay for both the units together.

EDIT: if you disregard the cost there is no question an MPPT is a better controller.
