TheSunPays 5.5kW high voltage inverter. Also a 4.8kWh SunPays battery.

Well great question, guess that is the obvious thing to do. Not sure why I didn't think of that first. See you can get one for R400-R500. Thank you.

Hi, I have a 5.5 kW inverter installed, with battery backup, and is in the process of adding 3.3kW solar panels. I know using solar PV panels to heat water is not the most efficient, but I dont want to buy another solar geyser if not required. I want to add my geyser to my my inverter output, but dont want it to use 2kW for a hour, but rather 1kW or less for 2 hours or even more while the sun is shining. Can I reduce the voltage to my existing geyser element to reduce the power usage (will still consume same energy, but less power over a longer period)? I see there are step down voltage converters rated for 4kW resistive (link below), so thinking if I drop the voltage with 25% the current would drop with 25% and power would drop roughly 50%. I can then use a smart switch to control this, so for around R1000 I can convert my geyser to solar. The element is just a resistor, so I dont think reducing voltage, current and power can harm it (not sure about the termostat?). Would this be technically possible and legal? https://www.geewiz.co.za/power-supplies/154048-ac-220v-4000w-variable-voltage-regulator-step-down-voltage-converter-transformer-motor-speed-fan-control-controller-ra.html?sfdr_ptcid=2961_617_675128575&sfdr_hash=b952de3a598d66c1434b14dda8043185&gclid=Cj0KCQjwmouZBhDSARIsALYcoup3sjW1xCpTOBHQjb7heiHPFuueAz8k9RIgBjU3kD-O2pbeao3ntdYaAor4EALw_wcB Regards, Chris

Good day, I have an existing backup storage for my home and home office, 5.5 kW inverter and 4.8kWh battery. I am looking to add solar panels and understand that I need to get approval from city of cape town first. My existing inverter is not on the CoCT approved list, so I think the system must be off-grid/alternative supply. I have an electrician (he installed the backup system a year or two back) and he has done PV installations before. He is a qualified electrician and said he can do the installation, but he does not have a seperate PV panel accreditation, is this required? I would like to submit my application, as I understand it can take months. Does anyone know what is required with this (a requirement on the appliaction): 'PRELIMINARY DESIGN - Please attach a schematic diagram design showing major components, proposed point of common coupling, isolating and interfacing devices with City of Cape Town electrical network, protection schemes, customer electrical installation, operating characteristics, etc' Anyone that can recommend someone for this design?
