PV-3 SOLAR DATA LOGGER
The PV-3 data logger is used by installers, householders, renewable energy companies to check PV (photo voltaic) installations. It can record solar irradiation up to 1,500W/m2 (watts per square metre), DC Voltage and DC Current produced by the panel, allowing you to assess the performance of a solar energy installation
Why is the Electrocorder better than other similarly priced competitors? The Electrocorder range use a constant sampling technique, unlike the single reading of competitors. When the loggers start to record, they sample every channel 16 times per cycle, a cycle is 16ms at 60Hz and 20ms at 50Hz. At the end of each averaging period, 3 quantities are saved for each channel, the TRMS average, the Max, which is the highest cycle value during the period and the Min, lowest cycle value. This means that it will record all the peaks and troughs which are one cycle or longer
When recording the Electrocorder will store the average voltage (and current if applied) over the period chosen (1 sec to 60 min), it will also record the highest (max) & lowest (min) cycle values during that period.
The voltage levels are stored with dates and times. With the back-up battery, the Electrocorder can continue to record for 4 weeks. An external 12Vdc PSU input is available, to allow for prolonged logging without batteries
