Posted February 9, 20241 yr First of all I need to say I am a pensioner basically living from hand to mouth. Say I only want a decent hybrid inverter with no solar panels to be recharged from the grid. I have two fridges a large chest freezer, a microwave and kettle connected to plugs. I have a TV and a MiBox and Open View Decoder, a computer with Wi-Fi and Fibre Modems and Six Backup Drives which are only in operation when being accessed. I also have a Fishpond Pump that is Echo Friendly and runs at .45 KW normally but runs at .75 KW for ten minutes after start up. I would ideally like the two fridges, chest freezer and Fishpond Pump to be isolated and only run on grid power. 1:- Can the Inverter be wired in to only power the plugs and lights but not the Stove, Hob and Geyser? 2:- What size Hybrid inverter would I be looking at to power my home for four hours of Load Shedding with enough Reserve Capacity not to deplete the battery / batteries completely? I would love some feedback and suggestions as to the practicality of my thinking.

In case somebody wants to refer you to a local business. RE your financial situation. The cheap way to get going here is some kind of lead/acid batteries. But with all the loadshedding we have, those are going to take a pounding and may not last long. Lithiums will cost you significantly more to get going, but they will last a lot longer, can be discharged to a greater depth, more regularly, and will be a better long term proposition. 15 minutes ago, Stew said: Say I only want a decent hybrid inverter with no solar panels to be recharged from the grid.

Yes. You can get an electrician to do that. It means changes to the DB thus a new COC will be required. 15 minutes ago, Stew said: 2:- What size Hybrid inverter would I be looking at to power my home for four hours of Load Shedding with enough Reserve Capacity not to deplete the battery / batteries completely? I would love some feedback and suggestions as to the practicality of my thinking. You've made a good start. Two pieces of information are required to get started, and I think you have or are close to the first 1) Consumption per hour 2) Peak momentary consumption across the backed up circuits. Thinking of your fridges and freezer, they are likely to draw more very briefly when the motor starts, then settle down. But it only needs a momentary overload to trip an inverter.

February 10, 20241 yr If money is tight get a trolley inverter and run a few extension cords Dont consider anything other than lithium as my sole experience in gel batteries resulted in a total write off after 90 days
