    sells a variety of electronic kits that can be used
    for powering 12 Volt equipment from solar power.

    Kits include:
    SCC3 12V/20A solar charge controller, withstands reverse polarity on both PV and Battery terminals
    BVM1 12V color-coded LED voltmeter with L.V. warning beeper, withstands reverse polarity
    DAS1 12V/10A dark-activated switch for automated lights, can be modified for
    light-activated operation which is useful for solar-powered beacons
    LVD1 12V/15A low voltage disconnect with auto-reconnect and L.V. signal

    Bundle two different kits and save $4.95, details can be found at

    These kits have been designed for power efficiency and have very low RF emissions.
    The kits use high quality double-sided silk screened PC boards
    that are manufactured in the USA, schematics are included.


    The photo shows a solar powered Ten-Tec Argo QRP transceiver that uses the
    SCC3 charge controller and the BVM1 low duty cycle LED voltmeter with a
    10 Watt PV panel and a 7AH lead acid gell-cell battery.

    Bulk discounts are available for ham clubs, send email for info.

    Satisfaction is guaranteed. If you have trouble getting your kit up and
    running, I will repair and align it for a small fee plus return postage. is a one person (ham) business in operation since 2000.

    Do you have anything that handles the bigger panels? The 48V 10A panels and can provide MPPT?

    Sorry, but my kits are all for 12V systems, the SCC3 charge controller kit can be modified to work on 24V systems.

    Keep in mind MPPT controllers have switch-mode PWM systems on both the PV panel and battery sides and as a result they tend
    to generate tons of RFI. A 48V system will probably need a DC to AC inverter, and that's yet another source of high-intensity RFI.

    Hi Forrest! The unit I bought from y'all many moons back is still going strong! It keeps a bank of 4 smallish AGMs topped up and ready. Thanks and 73!

    Was going to convert a regulated DC supply to interface my panels and battery until finding your adjustable
    charger. Hope to order soon, Thanks for producing a needed product!
