Solar Charge Controllers - KWT Tech Mart

Solar Charge Controllers

(22 products)

Shop Solar Charge Controllers at KWT Tech Mart to manage how power flows from panels into storage and protect battery health. Uganda's variable sunshine and unpredictable household loads make regulated charging crucial for longer battery life, and correct pairing prevents overcharging, overheating, and premature capacity loss.

Services & Support

Beyond supplying solar charge controllers, KWT Tech Mart can arrange installation through approved technicians; where arranged, installation is charged separately from the controller price. KWT Tech Mart, based at Cham Towers in Kampala, is who you contact to arrange that installation with an approved technician.

Buying Guide

Many installers prefer MPPT Charge Controllers because they track changing sunlight and push more usable energy into the battery bank, while PWM Charge Controllers suit smaller, simpler setups. Place the controller near batteries with tidy cabling to reduce heat buildup and voltage drop, especially in warm rooms — and use clear labelling in shared homes so anyone can check settings safely.

Cash on delivery is available for eligible Kampala orders. Returns within 7 days, subject to policy conditions. For delivery guidance or order help, WhatsApp or email KWT Tech Mart.

Solar Charge Controllers FAQs

How do I size a charge controller for my panels?

For a PWM controller, the current rating must exceed the panels' short-circuit current; for an MPPT controller, the rated charging current must cover the array's wattage divided by the battery voltage. Either type must accept the array's open-circuit voltage, especially with panels wired in series, and match your battery bank's voltage.

Does the controller need to suit my battery type?

Yes: lithium, gel and flooded lead-acid batteries charge at different voltages, so check that the controller offers a setting or profile for your battery chemistry.

What affects the installation charge for a controller?

The charge depends on how your panels and batteries are configured. Have the number and wattage of your panels, how they are wired, and your battery bank's voltage and type ready when you arrange installation.

Which features help me see that the system is charging properly?

Check whether the controller has a display or Bluetooth app that shows battery voltage, charging current and daily yield. A load output with low-voltage disconnect can also switch off connected loads before the battery is deeply discharged.

What delivery time and warranty apply?

Kampala orders are typically delivered within 1 business day. Orders outside Kampala add one additional business day for transit. Warranty terms, where applicable, vary by product and brand. Confirm the applicable warranty with KWT Tech Mart before ordering.
