Lighting Controllers

Application

A basic battery charge controller coupled with a basic light controller. This unit charges the battery by day and keeps the light on during the night until either the sun comes up or the battery is drained. This unit emphasizes extremely low cost and minimum interference.

This unit is available open frame as shown for mount in your battery box, in a plastic enclosure for indoor mount, or a NEMA 4 enclosure for outside mount.

Basic Operation

A major source of noise interference in PWM systems is the sharp voltage and current transitions that happen when the Series PWM switch very quickly connects and disconnects the panel current to the battery to control the charge.Add a large panel and long panel wires and you have a perfect antennae to transmit all this electrical noise being created.

This basic charge controller charges the battery by connecting the solar panels to the battery then shorts the panel (no power loss when shorted) and reconnects the panel to battery with PWM control. The battery sees a PWM style charge current with PWM control, however, since the panel current shorted is very close to panel current into the battery, there are no sharp transitions of panel current, hence minimal electrical interference.

An integral Low voltage disconnect shuts the light off if the battery gets to low. As well, as internal circuit turns the light on/off at nighttime/daytime. For extra flexibility, shorting the on/off connector with a switch turns the light off - an on/off light switch at night

Special Shipping Note:
All Solar Converter Products are behind in production. These items are usually shipped directly from the manufacturer in Canada. They cannot be shipped by any expedited methods such as UPS Blue or Red. They will generally be shipped via Canadian Express Mail which avoids import brokerage fees of $50-$60. Lead time on these products may be up to 4-6 weeks depending on their production. This is true of all Solar Converters products with the exception of the battery desulphator (item code SORBD-2) that we stock in our warehouse. If you want Solar Converters products to be shipped by normal Canadian Post, but would prefer to have the rest of your order to be shipped by a faster method, please write this information in your order's notes during checkout.
