Is there a program such as WatchPower to control settings with a computer for the MECER : SOL-I-AX-8M2

Thank you so much, that is clear and I understand.👍

Thank you for that, I agree there is confusion with the term Hybrid. Can you define the difference between Hybrid and Bi-directional inverter? A friend of mine starting out is looking at The MECER : SOL-I-AX-8M2 that was sold to him as a hybrid and told him I'd try to get clarity from the forum. I have a Goodwe 4.6 ES inverter which does indeed export excess solar power to non essential loads if there is extra power coming in and if we wish to use a non essential item eg Airconditioner, stove, etc. If there is not sufficient power available it will of course draw from the batteries or the grid, depending on the Mode settings.

Thank you @GreenFields have had a quick look and they appear to be a hybrid.

Can anyone confirm that a MECER : SOL-I-AX-8M2 sold as a hybrid inverter is actually a proper hybrid? I understand that a true hybrid can combine power from solar, mains and batteries to supply its rated output? In so doing the hybrid inverter can export excess solar power to non essential loads? The hybrid also has the ability to export power to the grid - if this is permitted? Some of the more popular true hybrids on the market in SA I believe are: Victron, Goodwe, Sunsync, Deye I would be grateful for comments Thank you

As the CT meter is clamped at the point of entry from the utility on the main DB, the only way to isolate (exclude) prepaid meter and the tenants sub DB , is to draw power for the tenant directly from the house-side of the Utility meter, via the prepaid meter.

Thanks everyone - issue resolved! We connected the Prepaid meter directly from the house side of the utility meter(Eskom), and then on to the subDB main for the granny flat, thus separating the tenant completely from the inverter, and so too, the CT meter.

Thank you I am going to look into separating the tenant from the inverter completely.

Thanks for your inputs GreenFields and Bobster - much appreciated, this issue is not yet resolved, and has come down, I think to completely isolating the tenant non-essentials from the inverter, and wonder if this is actually possible?

Hmm will run that by the installer? thanks

I'm not sure yet but there is a setting to prevent exporting to the Grid, which is set so.

OK thanks, Bobster, as I understand and know by experience is that in Back-up mode the battery is not discharged unless to support back-up loads when the grid is unavailable. I have mine set not to export as well. I have checked during the day when solar is active and found that the Aircon, and geyser , which have their own breakers, do not draw from the batteries but only the appliances on the plug circuit draw from the batteries i.e. stove, kettles, microwave fridge etc.

I am so sorry, this post was sent in error. The issue is not "drawing power during load-shedding". I tried to edit and remove but failed. Please see the post below. I have recently replaced a 5kW backup inverter with a 4.6 kW Goodwe es hybrid inverter and a 5kW Freedom Won e Tower battery both working very nicely. I have 2 strings of 6 PV panels generating about 4 kW during midday hrs on a good day I have a granny flat wired with a sub DB and a prepaid meter with the light circuit on the inverter as essential load so that during load-shedding the client can have lights. The non-essentials (aircon, stove, geyser, kettle etc ) are not energised during load-shedding of course. However during normal operation when there is no load-shedding in the hrs of darkness or when PV input is low I have noticed that the non-essentials from the granny flat, draw power from the batteries. This is not desirable because during hrs of darkness or low PV input, the client could trip the system by utilising the non-essentials excessively without the main house realising. Can anyone advise if or how this issue can be resolved? I presume it is a matter of wiring the sub-DB and or the granny flat non-essentials? Thank you

Prepaid meter drawing from battery during loadshedding

Thank you, my point is whether it is harmful for the batteries to only use 25 - 30% DOD every day?
