On cloudy days, sunlight is filtered through the clouds, creating something called diffused light. While panels can still convert this type of light into electricity, the output is usually lower, sometimes around 10% to 25% of the usual production, depending on how thick the cloud cover is.
[pdf] The optimal operating temperature for a solar inverter is typically within the range of 20°C to 25°C (68°F to 77°F). At this temperature range, the inverter's components can function efficiently without significant thermal stress or degradation.
[pdf] The SWP1500-DA72 is an inverter that converts a DC voltage from 72V to 230V AC alternating voltage (pure sine wave) and can supply an alternating current and a continuous power of 1500W. This way you always have sufficient 230V alternating voltage available.
