Grid Tied Limiting
ExSolar have developed a Grid Tie Limiting Device that caters for systems using either Fronius or Kaco Inverters. It also has a built in energy monitor which allows you to monitor your usage via our portal. It can be used for either 3 phase or single phase AC systems, and is more accurate than other systems available on the market that typically only estimate the voltage. It has 3 AC inputs for various power measurements, and 1 DC input to measure both battery voltage and current – typically used for monitoring battery banks.
Also available are a number of network modules for connecting the Grid Tie Limiter/Energy Monitor to our web-based portal: WIFI, Ethernet or GSM. The unit will then log and display per second readings. The unit is designed to measure bi-directionally on both the AC and DC current systems.
This device allows Solar systems to be able to “follow the Load” and not over-produce, therefore it prevents pushing energy back to the grid. This feature is especially necessary for installations with Digital or Pre-paid meters (which bill the client when energy is pushed back to Eskom).
