[QUOTE="wolfandy, post: 1135529, member: 13737"] Correct. Even with the kettle by itself she would need to be careful. Some kettles draw 2.5kW - and depending how the rest of her load is at that point, it might already overload the inverter Thanks for the detailed item list. The 3.6kW Sunsynk does not make sense to me. For [URL='https://www.solar-shop.co.za/sunsynk-deye-hybrid-inverters/406-sunsynk-5kw-hybrid-inverter.html']R26k incl VAT you can get the 5.5kW version[/URL] (even though currently not available, but stock usually comes in on a regular basis) 3x solar panels does not make sense. This is barely enough to get the MPPT in the inverter started, which will result in potentially erratic behavior of the MPPT and potentially very little solar production. If solar panels is a requirement, then she would need to get at least 5 panels. Not sure of the detailed specs of the panels, but one can probably connect up to 9 of these panels Maybe please also ask what the purpose of the system should be? Cover 2h of loadshedding? Or 4h loadshedding? Or generally generate own power and reduce Eskom bill as much as possible? This has an impact on solar panels and battery size [/QUOTE]
