MPPT Maintenance
The following inspections and maintenance tasks are recommended at least two times per year for best performance. Make sure no block on air-flow around the controller. Clear up any dirt and fragments on radiator. Check all the naked wires to make sure insulation is not damaged. Repair or replace some wires if necessary. Tighten all the terminals. Inspect for loose, broken, or burnt wire connections. Pay attention to any troubleshooting or error indication .Take corrective action if necessary. Confirm that all the system components are ground connected tightly and correctly. Confirm that all the terminals have no corrosion, insulation damaged, high temperature or burnt/discolored sign, tighten terminal screws to the suggested torque. Check for dirt, nesting insects and corrosion. If so, clear up in time.
This solar controller is based on an advanced maximum power point tracking (MPPT) technology
developed, dedicated to the solar system, the controller conversion efficiency up to 98%.
The controller can rapidly track the maximum power point(MPP) of PV array to obtain the maximum
energy of the panel, especially in case of a clouded sky, when light intensity is changing continuously, an
ultra fast MPPT controller will improve energy harvest by up to 30% compared to PWM charge controllers.
Current Boost Under most conditions, MPPT technology will "boost" the solar charge current. MPPT Charging:
Power Into the controller (Pmax)=Power out of the controller (Pout) Iin x Vmp= Iout x Vout* Assuming 100% efficiency. Actually, the losses in wiring and conversion exist. If the solar module's maximum power voltage (Vmp) is greater than the battery voltage, it follows that the battery current must be proportionally greater than the solar input current so that input and output power are balanced. The greater the difference between the Vmp and battery voltage, the greater the current boost. Current boost can be substantial in systems where the solar array is of a higher nominal voltage than the battery as described in the next section.High Voltage Strings and Grid-Tie ModulesAnother benefit of MPPT technology is the ability to charge batteries with solar arrays of higher nominal voltages. For example, a 12 Volt battery bank may be charged with a 12-, 24-, 36-, or 48-Volt nominal off-grid solar array. Grid-tie solar modules may also be used as long as the solar array open circuit voltage (Voc) rating will not exceed the maximum input voltage rating at worst-case (coldest) module temperature. The solar module documentation should provide Voc vs. temperature data. Higher solar input voltage results in lower solar input current for a given input power. High voltage solar input strings allow for smaller gauge solar wiring. This is especially helpful and economical for systems with long wiring runs between the controller and the solar array.
Traditional controllers connect the solar module directly to the battery when recharging. This requires that the solar module operate in a voltage range that is usually below the module's Vmp. In a 12 Volt system for example, the battery voltage may range from 10.8-15 Vdc，but the module's Vmp is typically around 16 or 17V. Because traditional controllers do not always operate at the Vmp of the solar array, energy is wasted that could otherwise be used to charge the battery and power system loads. The greater the difference between battery voltage and the Vmp of the module, the more energy is wasted.
Nominal 12 Volt Solar Module I-V curve and output power graph. Contrast with the traditional PWM controller, MPPT controller could play a maximum power of the solar panel so that a larger charging current could be supplied. Generally speaking, the MPPT controller's energy utilization efficiency is 15%~20% higher than PWM controller. Conditions That Limit the Effectiveness of MPPT The Vmp of a solar module decreases as the temperature of the module increases. In very hot weather, the Vmp may be close or even less than battery voltage. In this situation, there will be very little or no MPPT gain compared to traditional controllers. However, systems with modules of higher nominal voltage than the battery bank will always have an array Vmp greater than battery voltage. Additionally, the savings in wiring due to reduced solar current make MPPT worthwhile even in hot climates.
