  1. https://www.sustainable.co.za/solis-4g-12-0kw-dual-mppt-3-phase-grid-tie-inverter.html Anyone heard of this before? Dual MPPT, is that for charging as well?
  2. Hi There, I have actually decided to just replace my 3kW heating lement in my geyser with a 1.5kW element, it might be under powered and run longer, but it frees up some kW's during the ay.
  3. I think you have me convinced. I have looked around the forum for reviews on the items i have, but did not find that much. I think i'll be going with the Multiplus II's and i'll still need to check how many MPPT's i can get away with. Lemme draw up a new list and get back to y'all
  4. Wow, thank you so much for the thorough rundown and real life experience. I am a tinkerer by nature, but i do have a certified electrician that will be overlooking the installation. Just to make sure the world is safe, and our family is safe, so I'll be doing the installation myself with a pair of eyes over my shoulder, this is the only way i will learn and fully understand what i am doing, in case i need to tinker with it later on. I'm now considering this: Inverter: Infinisolar 10kW 3Ph Hybrid On-Grid Inverter - Yes, it is a bit more pricey than one MultiplusII, but, it is already giving me 3.3kW over each of my 3 phases. It does limit me to 10kW at the end, but i am sure one MUST be able to live with 10kWh For Batteries i am considering BYD 10Kwh Lithium Ion 48V Battery Bank, but only because it is around 10k cheaper than the pylontech 9.6kW alternative. With the above setup i can get the following: 1 Pallet 72 Cell 330w PV Modules (256 modules on the pallet) @ R 48,334.00 incl VAT Infinisolar 10kW 3Ph Hybrid On-Grid Inverter @ R 41,743.00 incl VAT BYD 10Kwh Lithium Ion 48V Battery Bank @ R51,635.00 incl VAT This comes to a total of: R141,712.00 leaving me 8K for a few bibs and bobs. What do you think? MY biggest concern with the infinisolor inverter, is the max input which is 14.5kW ... this basically means i cant get a solar array bigger than that and i am also not sure if i can string these together either. oh, and yeah ... me... living in a regulated area ..... NEVER
  5. I found this deal: https://www.gwstore.co.za/product/rct-infinisolar-10kw-3ph-hybrid-on-grid-inverter/
  6. Hi There, Has anyone used or heard of this inverter before? Can anyone comment on the specs? https://solaradvice.co.za/product/omnipower-plus-10kw-3ph-hybrid-pv-inverter/ EDIT argh .. its 3-phase nevermind
  7. https://www.takealot.com/6000w-48v-grid-hybrid-solar-power-inverter-with-mppt-charge-controller-blue/PLID40402154 Anyone hear of skyking before?
  8. I feel like i am in waaay over my head here... From my understanding cutting the bill and having power backup is all doable by using the proper equipment. and from what i have learned so far is getting a hybrid inverter goes a long way in achieving this. I can over generate power during the day using pv modules, and charge batteries as well as draw current directly from the solar array. When the power goes out (loadshedding) i should have battery backup.
  9. I can spend around 40k on a hybrid inverter and charge controller (not sure if some inverters come with a cc?) right now i am working from 2 sites ... sustainable.co.za and herholdts.co.za. I dont always understand the accronyms, but does some inverters come with a charge controller?
  10. nope.. i have no 3 phase appliances.
  11. I have not purchased anything yet. I have around R150k to start off with My immediate need is to have backup during load shedding. BUT, i need it to be scalable as i will have 200k additional funds in 7 months, and i would prefer not to re-purchase items due to scaling.
  12. Hybrid, so that when the batteries run out i can use municipal powe
  13. @Chris Hobson which inverter would you then suggest?
  14. @Chris Hobson I have three phases coming into my db board. if i can somehow only use one of those phases i can go with a single phase inverter. or if it is possibl to combine them. Thing is... i have no 3 phase equipm,ent, so the three phases is not a requirement. unfortunately it is what is laid to my db board. Sorry, i have done as much research as a can but the whole concept still eludes me
  15. @Chris Hobson any suggestions on an inverter that will be able to run the batteries as well? that is grid-tied? or any alternative setup that will achieve my goal
  16. Hi There, Can anyone comment on my below components. Inverter - https://www.sustainable.co.za/solis-4g-12-0kw-dual-mppt-3-phase-grid-tie-inverter.html Battery bank - https://renewables.herholdts.co.za/product/byd-10kwh-lithium-ion-48v-battery-bank-complete/ Solar Panels (x20) - https://renewables.herholdts.co.za/product/canadian-solar-72cell-310w-pv-module/ Charge Controller - https://renewables.herholdts.co.za/product/victron-bluesolar-mppt-250-100-tr/ Geyser - https://www.sustainable.co.za/gap-eco-green-200l-direct-solar-geyser.html What am i going to use it for? Always on: Fridge Freezer Wifi router Day Time: TV Computer 1000W Aircon Borehole (2.5kW) Washing mashine Iron. Night Time Lights TV Computer Note, that this is not an entire off-grid system, it is to save power where possible. So it is grid-tied. I currently use around 50kWh a day, i am looking to more or less halve the usage. I will be replacing all lights with LED lights, replace my geyser and replace two additional geysers with gas geysers The geyser will hopefully heat up during the day. I am also going to change habbits to do as much power hungry tasks during the day. Am i being realistic at all? and, the above mentioned equipment, are they compatible, also, am i missing any BIG ticket items that is obvious?
