This DR 3624 comes with the temp. sensor also. Shown installed at my home I ran this for over a year as a battery backup system with 8 - L16s and my 16' axial. Grid power as a charger and for equalizing, this inverter is like brand new. I can say this with confidence as I know the history. I have moved up to 48 volt for my solar voltaic which is why I am selling this inverter. This unit weighs 45-50 lbs. and is located in Western NY. $600.00 Shipping and or delivery options negotiable.

rated 3600 watts.)
