I am responsible for designing a solar PV and Solar Thermal system for a Rural Guest House in Ghana.
We need to understand what the electricity usage profile is so we can design the correct system, and unfortunately, the existing fiscal electricity meter seems to have been tampered with as the usage is tiny - 700kWh per month for a 15-bed hotel, with a large bar, restaurant area and small library.
So really what I need is simply a single-phase CT clamp data logger, 100A should do. no remote monitoring is required. however, the dataloggers that I find online are very £££. so preferable i would like to use a open energy monitor type solution.
there is no Wifi, or 3g connection at the site.
all suggestions appreciated.
