[Elecraft] Solar Controller Kit
Hi There seems to be some confusion about my two controller kits The High power controller will work fine with a small panel. The kits are identical except for the blocking diode and power FET. The low power uses a 6 amp FET and a 3 amp diode while the high power uses a 75 amp FET and two 8 amp diodes. You can also add a second 3 amp diode to the low power kit to increase the power to about 70 watts. If you think you may go big at some time I would suggest the high power kit. I have used the high power controller with a 110 amp hour gel cell battery and 150 watts of solar panels as well as a 2.6 amp hour battery and a 3 watt solar panel and it works great with either. The low power kit is less expensive and is fine for small panels. A 3-5 watt panel and a small SLA battery of 2-7 amp hours works fine for a K1 or KX1. A QRP K2 would need a 10-15 watt panel with the same battery. A K2/100 would need a 35 to 100 amp hour battery and 80 to 100 watt panel. All of this this explained in the documentation and application notes that I supply with the kit.

[Elecraft] Solar controller Kit
Hi I have been supplying a Solar Charge Controller Kit for several years. This controller will keep a SLA or LA 12 volt battery charged from solar panels of 3 to 150 watts. Batteries of 2 amp hour to 110 amp hour have been used with these controllers. I am currently sold out of the kits but I have just ordered another batch of circuit boards that should be here in about 3 weeks. The kit is $30 check or money order and includes all the parts and documentation required to build the controller, less a box to mount it into. I still have a few of the low power version of this kit (1.5 amp) in stock at $16. This kit will supply plenty of power to charge a small SLA battery for a K1, KX1 or QRP K2. order from: Don Brown KD5NDB 19132 Falls Creek Drive Flint, Texas 75762 Thanks Don ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
