The OutBack MX60 is Rated for up to 60 amps of DC output current, it can be used with battery systems from 12 to 60 vdc with a PV open circuit voltage as high as 140 voc. The MX60’s setpoints are fully adjustable to allow use with virtually any battery type, chemistry, and charging profile. The OutBack MX60 allows you to use a higher output voltage PV array with a lower battery voltage - such as charging a 24 vdc battery with a 48 vdc PV array. This reduces wire size and power loss from the PV array to the battery location while maximizing the performance of your system and saving you money!

The Sunforce 7 amp Charge Controller prevents overcharging of 12-volt batteries and is intended for use with 12-volt solar panels.

The Kill A Watt Meter will help you reduce your energy use and save money on your power bill. Use it to find power-wasting appliances in your house and keep track of total kilowatt-hours used. Displays Volts, Amps, Watts and Frequency. The list price on the Kill A Watt Meter is $39.00, but I found it for $22.98.

The new SMA Sunny Beam Wireless System Monitor is a PV geeks dream. Now you can remotely monitor the performance of your PV system (without wires!!!) on a large, easy to read LCD screen. Get a real-time display of AC power output, daily and total energy yield displays and daily energy yields for the current month or the last 31 days. It even has a built in solar cell to supplement internal batteries. I need to point out this monitor is geared towards the new inverters (i.e. SB 3000, 4000, 5000, 6000 and 7000) and will NOT work with the old family of inverters (i.e. SB 700, 1100, 1800, 2100, 2500, 3300, 3800 and the old chassis 6000).

Fronius International is a world market leader in high frequency welding technology and one of the leading photovoltaic inverter manufacturers. The Fronius IG 4500 Inverter outputs up to 4,500 watts and weighs only 42 pounds. Optional remote data communications and data logging features can easily be added via Plug-n-Play cards to transform IG inverters into a sophisticated data acquisition system and weather station.
