80A Smart MPPT Solar Controller

AP-80C MPPT Solar Charge Controller – Manufactured by Foshan Top One Power Technology Co., Ltd.

The AP-80C is a high-performance MPPT solar charge controller from Foshan Top One Power Technology Co., Ltd., a company based in Foshan, Guangdong that has been manufacturing power conversion equipment since 2003. It's part of their AP Series and is designed for large off-grid and hybrid solar systems that need serious current handling capability.

What makes the AP-80C stand out is its tracking efficiency-it hits 99.5% MPPT tracking accuracy, with charging conversion efficiency up to 98.6% and full-load efficiency of 96.6%. That means less energy wasted and more power actually going into your batteries. The controller works with 12V, 24V, 36V, and 48V battery systems, and the MPPT operating voltage range varies by system voltage-for a 48V system it's 60V to 150V, which gives you flexibility in panel configuration.

The AP-80C handles a maximum PV array power of 1140W for a 12V system, all the way up to 4540W for a 48V system. It supports multiple battery types-sealed lead-acid, gel, NiCd, and LiFePO4 lithium batteries-with a three-stage charging profile: constant current (MPPT), equalizing charge, and floating charge. That charging algorithm adjusts automatically to protect battery health and extend service life.

One practical feature is the two operating modes: charge priority and load priority. You can also run it in battery-free mode, where photovoltaic panels power the DC load directly. There's an RS485 communication port for remote monitoring, and the LCD display gives you real-time data on input voltage, output voltage, charge current, and system status. Protection covers overcharge, short circuit, reverse polarity, and over-temperature.

Backed by Foshan Top One Power Technology Co., Ltd.'s ISO9001-certified manufacturing and CE, EMC, and FCC compliance, the AP-80C delivers reliable, efficient performance for serious solar installations.
