Aitoserlea Solar Panels Editorial Review
The WS400A PV Cell Meter is a device that tests solar panels and provides readings for enthusiasts and DIY PV cell private installers. It has a banana plug that makes adding adapters easy to analyze solar panels at max 100 watts. The upgraded model has an LCD display function that makes it easier to read when testing is done outside. Overall, the WS400A PV Cell meter seems to be effective in aiding users to assess their solar panels' wattage and current output. However, the device's display does not live up to expectations, especially regarding readability in direct sunlight. Moreover, the amperage displayed was sometimes off, and voltage measurements were sometimes misguided compared to the fluke meter. In general, the WS400A PV Cell Meter helps diagnose bad panels quickly and saves you a lot of time and money by avoiding costly replacements. It is a good device for those who need a one-purpose device.
