You can use this with up to 6 GC1000 Inverter systems. It is completely digital and can be hooked up to your computer for detailed monitoring.
This would be a great monitor if you need it and for the price I will sell it for it is more than worth it. These sell new for $700 and up, I will sell this one for $500 OBO. Any offer fairly considered. Look this up on the web, you will see that this is a great deal!!!
For any other info on this product or for pictures e-mail me and I will promptly respond. This is new in the box and has the full 92 page binded user manual. Everything is in excellent condition and comes with the disc for using this in conjunction w/ your computer.
I have a paypal account for payment and I will provide a tracking # for you as soon as payment is received.
