It converts panel output at roughly 93-97% efficiency against 75-80% for PWM units.\"}},{\"@type\":\"Question\",\"name\":\"Is MPPT better than PWM for electric fence energizers?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"For a single small fence energizer, PWM is adequate and cheaper. Once a second device shares the same battery bank, MPPT's higher efficiency and load output terminal make it the better choice.\"}},{\"@type\":\"Question\",\"name\":\"What amperage charge controller do I need for a CCTV system?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Amperage is sized from total panel wattage, not just the camera draw. A hybrid MPPT controller with LCD and load output covers most home and small-office CCTV backup setups without oversizing.\"}},{\"@type\":\"Question\",\"name\":\"Can one controller run both a 12V fence energizer and a 24V gate motor?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Only an auto-sensing 12V\/24V controller can, because it detects battery voltage automatically. A fixed-voltage controller cannot safely serve both banks.\"}},{\"@type\":\"Question\",\"name\":\"How many peak sun hours does Kenya get for solar security systems?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Kenya typically sees 4 to 6 peak sun hours a day depending on region and season. Use that figure when sizing a panel and controller for a security load.\"}},{\"@type\":\"Question\",\"name\":\"Do I need a load output terminal on my charge controller?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"A load output terminal helps when running DC devices such as cameras or sirens straight off the controller instead of wiring them to the battery. It simplifies installation but is not mandatory.\"}},{\"@type\":\"Question\",\"name\":\"How does a low-voltage disconnect protect my security battery?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"It cuts power to the load once the battery drops below a safe voltage, preventing the deep discharge that shortens battery life.
