Hi Guys I need advice to start a "from nothing to something" system. I did ask on another 4WD forum and after the first 3 decent replies and offers of help it degenerated into a bun fight and I unsubscribed from my own post. The scenario is I plan to downgrade in house to something smaller designed "green" in a few years time (with gas and solar geyser etc) - I would like to start a system that can be moved when that time arrives, also continue to add to it. So time scale is say life of first batteries (5 to 10 years) 1. Run lights (LED's) - say 20 2. Run PC's & TV's - say 2 of each and one HiFi. 1 Printer used infrequently 3. 1 energy efficient Fridge/freezer + 1 Energy efficient freezer 4. 1 Washing machine every 2/3 days (I presume there are energy efficient that will be purchased at that time) 5. Highest envisaged load will be a single plate induction cooker 2,2 kW and a hair dryer once a day (under duress) 6. There will always extras I know - guidance from you guys will be appreciated Envisaged 1. A double or 2 single carports using solar panels as the roofing, designed by Pr Eng. to handle load and wind 2. House (old and new) will still be connected to EKSDOM, new house will have a separate DB for "New System". There will be then grid backup for rainy days etc 3. 3kW Victron panel? But probably the 5kW would be more logical see image attached - This is where even I, as a Millwright and a Mech Eng. get lost. I like it as it seems to me to be a system that can be added to as finance allow. 4. So, one of the Victron Jobs (image attached), with 1 Carport, 2 Solar panels and one set of Batteries....then add on every few months. I like the attached panel as it has a dedicated grid powered output with the balance from the system. 5. Batteries? Yip 12v completely wrong I know, 24 v better but batteries will work too hard and way higher Amps. So 48v rather? 6. Deep Cycle? Notoriously difficult to get to 100% charge, better cycles and DOD, Semi-deep/Leisure/marine? Easier to charge not as many cycles, good DOD. Lithium and Star Trek batteries - Rather wait the 5 to 10 years for technology to catch up Feel free to give advice, even suppliers please. Knowledge is power. It will be a DIY system and short extension cords for now with no Home DB connection except for the one input, new home will be a proper installation with a qualified Tech into a DB. Am I on the right track - Thanks for reading my long winded question
