Have a listen to the interview with Nersa re the withdrawal. https://omny.fm/shows/the-john-maytham-show/home-grid-registration

I drive by each day - Unit 11 is for Hitek Electrical. There is no SetSolars there - so agree, very fishy.

I think this is the same as the ebay one. I've used the company - just had delivery of two Arduino Mega's today. Building my own Differential Controller. https://www.robotics.org.za/index.php?route=product/product&path=57_131&product_id=320

Hi If my understanding of the SSEG costs are correct, you need to be pushing back about 22kWh per day to offset the R13 daily SSEG charge at the R0.57/kWh feed in tariff they pay. This is not a solution for the Residential user - more for businesses maybe who are producing lots more power. Andrew

Is the Microcare Grid Tie Limiter not also tied to the Microcare inverters?

Sounds interesting Mike. Looking forward to your feedback. Anyone had any experience with the Ex Solar solution - http://www.exsolar.co.za/products/grid-tie-limiter/ - much more expensive than the Microcare option at around R6k though.

Thanks superdiy Apologies for my ambiguity. I would control the load with timers - geyserwise for the geyser or pool pump timer. I was thinking more along the lines of only setting the timer to start the load around about the time that power from the PV > 50%. But before then I would have excess power from the PV as I would only be providing power to my parasite loads which is on average around 200W. To avoid the expense of the batteries and accepting that with loadshedding I would have no power I was looking for a solution to prevent the reverse power flow onto the grid. Hence the query re the grid tie limiter. For now, I have a generator for load shedding times should I need to power the lights at night. Batteries are down the line at this time in my planning and finances.

Resurrecting an old topic, but I haven't seen much comment on it. What is the success with using the Grid Tie Limiter? I'm wanting to install a Grid Tie System and was all excited until I saw the SSEG limitations by City of Cape Town where you're required to install a reverse power flow blocking system. I plan to move load to run during the day (Geyser in winter - I have a flat plate solar heater system but it doesn't get the water up to temp in winter / pool pump in summer and the parasite load running 24/7) but early morning before the sun comes into its own I don't want to start that load and incur Eskom costs. Added to that my, googling has me only finding two manufacturers on the market - Fronius (through ExSolar) and MicroCare (which does not appear on the CoCT Approved PV Inverter list). Are there any others?
