SPECIFICATIONS Application: Charger Controller,Solar System Controller 60A 80A 100A Solar Charge Controller 12V/24V/36V/48V Regulator Battery Charging Controller Max Solar PV 150V Dual Fans Certification: CE Is Smart Device: no Maximum Current: 100A is_customized: Yes HHJ-80A / HHJ-100A Features High-efficiency MPPT technology: Conversion efficiency up to 98%, MPPT real-time tracking efficiency **>99%**, maximizing power generation in both strong and weak light conditions. Wide voltage compatibility: Supports 12V/24V/36V/48V systems, manual voltage selection, suitable for off-grid/hybrid PV systems. Wide battery compatibility: Compatible with lead-acid (sealed/gel/float) and lithium iron phosphate (4-cell/8-cell/16-cell), supports user-defined parameters. Three-stage charging: Fast charging → absorption → float charging, improving efficiency and extending battery life. Comprehensive protection: PV reverse connection, short circuit, overcurrent, battery overcharge/over-discharge, load overload, over-temperature protection. Human-machine interface: LCD screen displays voltage/current/power/temperature/fault codes; button settings for parameters and factory reset. Installation and Heat Dissipation: Indoor installation, vertical wall mounting, forced air cooling, operating temperature **-35℃~+45℃**. The difference lies in the specifications: The HHJ-60A solar controller supports a maximum charging current of 60A, a maximum PV input power of 2800W, and a PV open-circuit voltage of 155V. The new 80A/100A models support a maximum PV input of 155V, compatible with monocrystalline/polycrystalline modules, such as LONGi 370W modules (open-circuit voltage 40.2V), which can be connected in series in 3 strings. The load port design is retained, offering greater flexibility (DC-5A).
