Solar Mini Charge Controller 42W Pk

Description

Solar Mini Charge Controller is a small form factor weather resistant controller used with small from factor solar modules/panels up to 42W Pk output rating. Ideal for charging small field monitoring equipment setups. Designed to be used between the battery of the solar system and the PV panel. Complete with power leads and 2 MC4 connectors for rapid connection of the solar panel.

Features full Lead Acid battery charging profile, automatic solar disconnection when solar voltage drops bellow a preset threshold, over voltage protection, trickle charge, float charge and automatic battery recharge and automatic battery recovery.

Automatic solar disconnection
If the solar voltage drops too low the solar module will shut down into standby mode to prevent drain on the batteries

Float mode
Once the battery reaches 90 of nominal charge it enters float mode to compensate for internal power losses and prevent over charging which reduces battery longevity

Automatic Battery Recharge mode
in float mode if the battery voltage gets drawn bellow 85% charge it will reapply the charging profile until it reaches float charge. this will occur if due to drain on the battery such as load being applied or self discharge over time

Automatic Battery Recovery Mode
The Charging will start recovery mode of dead or over discharged batteries who’s voltage has not gone dropped bellow 8v. It will do a slow trickle charge until a nominal voltage has been achieved at this point it enters a full charge and condition cycle culminating in float charge monitoring.

Technical Info

Recommended solar panels 10,20, 2x 20w (2 in parallel) 12v panels with Voltage open Circuit of >= 26v.

to ensure longevity of the controller we we recommend not exceeding 40w actual output.
