Subject: Solar Boost 50

Gentlemen,
       I am using two of your SB 50's controlling 5 pair of 75 watt panels each. The system is a 24 volt system, on the average I was producing around 45 amps per hour. With the SB 50 's that number has increased to 65 amps per hour. I also have noticed an increase in the usable current on the low end. The SB50's are the best investment we have made to date. I have seen a definite improvement in the batteries charging and storage. The system I run sits in the middle nowhere in upper Wisconsin and  has the following equipment.

2 Trace 4000s in parrel= 220volts

1 Whisper 3000 with current diverter.
2 5 pair 75 watt panels on a tracker.
1 20kw Onan LP generator
2 SB 50's
Assorted batteries equaling 1800 amp hours availability. Mainly Trojan batteries.

Thank You again for a great product.

Reno J. Fechtner.
