Posted January 12, 20232 yr Hi all, Looking for some help please, I have done a ton of research however I am not finding anything conclusive. I would like to a full built in invertor that can keep my home running during load shedding. I would like to do this properly the 1st time and with a reputable provider. I have a 3 bedroom house with a solar and powered geyser and have the following items... Console, 65inch tv, 3 x pc's with 2 monitors and the rest is the normal applicances (2 x Aircon, oven, fridge) and lighting. I was looking at the Sunsynk 12KW with solar panels but not sure what is my best option, so any advice would be greatly apprecaited! The portable devices and trolleys are cool but would prefer something integrated with the DC which covers the house. Something to note is I do not need to use the oven during load shedding. I am based in the Cape. Thanks in advance peeps!
January 12, 20232 yr The 12kw SS is a 3-phase system. Do you need 3 phase power? The amount of power on each phase is also limited - i think its 6-3-3 but i could be wrong. Have you done a power audit - even for day or so to understand your peak usage and usage trends?

HI there thanks for the reply, to be honest I don't even know what 3-phase details I do not think I require this I just want to power the household so open to any suggestions. I have also not done a power audit but I will do this so I know what kind of usage I have. I am pn pre-paid so i will take a heavy usage day (usually weekends) and determine what usage I have. Thank you!
January 12, 20232 yr If you didn't even know about 3-phase then its likely your place is single phase (as are most houses). An audit will help you size the inverter and batteries that you'll need for your setup. At a very high level (don't quote me) you should be fine with an 8kw inverter and 5-10kwh battery + 8-16 panels. But lets get the data first and see where that lands us. What is your budget?

Amazing thanks Mzezman, apprecaite the help! I will feedback with the usage asap.

Also just got confirmation I am on single phase

Thank you! Its a good start the prepaid meter useage - but it won't tell you your peak and average load requirements. You will need something like the Efergy Energy Meter to do this - its a bit pricey but is also a useful gadget to keep even after your install is done.

January 12, 20232 yr Get an idea of 1. Average KWH consumption per day = idea of no panels and battery requirements, size of inverter 2. What is maximum load at any time (without a meter need to calculate using appliance watt specs) = size of inverter 3. Average KWH consumption at night (winter = 16+ hours) = battery size If you are going to jump in then consider more than the just loadshedding, look more at investing in reducing your need to use Eskom as little as possible. The big bucks are in what you don't pay to Eskom. The returns on the investment is that money that you would pay to Eskom, that you would be paying back to yourself, and after 6/7 years will make a profit for you because the system will be paid off and that money goes directly into your bank account. A loadshedding solution works out to be a convenience but saves very little. Scrap together as much as you can in the beginning, and/or plan a schedule to upgrade to the final solution https://globalsolaratlas.info/map?c=-31.358328,19.660034,7 is a good site to get an idea how much solar you can generate in summer/winter at your location https://app.opensolar.com/#/home allows you to build and test solar solutions, including shading issues - free account You can provide me your location and your expected average KWH usage per day, and I could build a energy profile for you Edited January 12, 20232 yr by AndrewinPlett
