![]() These functions are described below: Solar Power Indication (POWER LED-red) ON: Indicates solar panels have proper connection and solar power source supplied. Any-Grid Battery Inverter Charger PSW-B (1.The 6 LED lights indicate charging status and battery conditions.Sensing and control circuitry continually monitors the battery voltage, environmental conditions and load current to prevent any situations that would be harmful to either the battery bank or the DC load.įor 20+ years, Phocos has supplied proven, robust PWM and MPPT solar charge controllers. The battery supply is powered through connected DC loads through the MPPT solar charge controller’s load switch. In case of shading where multiple local maximum power points occur, Phocos’ MPPT algorithm always tracks the global maximum power point. This is important as PV-voltage at the point of maximum power output varies over irradiation and temperature. When the battery voltage is less than the targeted charging voltage, the MPPT solar charge controller implements maximum power point tracking to maximize all available power from the solar PV array. Sensing and control circuitry with an MPPT solar charge controller algorithm continually monitors the battery voltage, environmental conditions and PV solar input to ensure proper battery charging. An MPPT solar controller regulates solar power input and converts it to charge power output compatible for the battery bank. The solar charge controller itself is powered by the battery bank. Phocos MPPT (maximum power point tracker) charge controllers consist of highly efficient DC/DC-converters that actively convert the higher solar panel input voltage to the lower output voltage level (battery voltage) for the battery bank, with only minimal conversion losses. Features like datalogging, lighting controls, and/or software/applications, allow for more flexibility to suit application specific needs.Īmong the range of Photovoltaic (PV) charge controllers, Phocos offers both PWM and MPPT versions. When advanced features are required for certain applications or in certain rigorous environments, selecting the right solar charge controller can make a significant difference for reliable performance.This helps to easily monitor system status and when needed, aids in troubleshooting. A solar charge controller typically shows system status information through LED indicators or display screens.A solar charge controller prevents reverse current flow to the solar PV panels at night, preventing wasted energy.If designed correctly, the right solar charge controller saves customers time and money to avoid costly, inconvenient downtime and unnecessary battery replacements more often than is standard for an application. This important battery care creates system reliability and maximizes the life of a battery bank. Preventing overcharging and over discharging of the battery bank will avoid battery damage. The solar industry identifies this as ‘optimizing’ battery charging. ![]() ![]() It helps to maintain energy production that operates in the range where a specific battery brand, location, temperature range, application, and/or technology operates best. A solar charge controller protects the battery investment.Why Use a Solar Charge Controller in an Off-Grid Solar System Design? Basically ‘controlling’ the charge to make the Off-Grid solar system operate smoothly. ![]()
