12V 10A Solar Charge Controller for Traffic Signal Systems

This component manages the charging and load connections in a solar-powered traffic signal installation. It connects the solar panel, battery and DC load; the traffic signal controller separately determines the signal sequence and timing.

Use it when assembling or replacing the charging section of a compatible 12V solar traffic signal system. Select the battery and panel together with the load schedule, rather than using the charging-current rating alone to estimate operating time.

The compact aluminium alloy enclosure has a silicone-sealed construction and a grooved base. Allow space around the housing for the leads, mounting hardware and service access.

Solar panel connection

Connect a compatible PV panel. Confirm the permitted PV open-circuit voltage, input current and panel configuration for this model before selecting the panel.

Battery connection

Use a compatible 12V battery system. Confirm the battery chemistry, capacity and charging settings; a nominal voltage match alone does not establish battery compatibility.

Load connection

Connect the approved DC traffic equipment through the load circuit. Keep the total connected load within the 8A output limit and check startup demand as well as normal operating current.

The photographs identify the panel, battery and load connections. Use the wiring diagram and polarity markings supplied with the unit; do not determine terminal assignments from wire colour alone.

1. Confirm the component combinationProvide the battery data, panel electrical ratings and load schedule. Confirm charging settings, PV input limits and any low-voltage disconnection settings before integration.
2. Plan the mounting and protectionCheck the available space against the housing dimensions and allow clearance for the cables. Select wiring and circuit protection for the approved system design and installation conditions.
3. Connect using the supplied instructionsA qualified installer should isolate the relevant circuits, verify polarity and follow the connection sequence on the supplied unit and its wiring diagram.
4. Check operation before deploymentCheck charging operation, load current and the connected traffic equipment through its required operating cycle. Record the settings and inspect the connections before commissioning.

Battery chemistry support, charging method, PV input limits and protection thresholds must be confirmed for the supplied version. Do not assume MPPT, automatic 24V operation or a specific battery type from the product name.
