Inverter nightmare

You have to find that balance between cycles and capital outlay. Good batteries cost a fortune but have high cycles. But can you finance them or be content with lesser batteries but replace them every few years? I went the cheaper option for 2 reasons. I couldn't afford top range batteries. And I didn't know whether I needed to add batteries at a later stage. You don't want to be mixing new and old batteries. So I figured 500 cycles would do me fine, but I'm expecting many more because I'm running about half the expected load. (ie the fridge can handle 4 or 6 hours of load shedding a day, but I need my streaming porn documentaries, light etc)

totally agree, i am very disciplined when it comes to batteries with everything, my phones never drop below 70%
people that run to 0% are bloody idiots

Lithium also have a limit to the number of cycles. They can be discharged further, but remember cycles are cumulative, so discharging a battery by 25% will take 4 charges to make a cycle. Discharging to 50% and its 2 charges to make a cycle. Lithium batteries can go below 80%. So one charge is nearly a cycle.

Yup and modern ones are good for several thousand cycles.

Phone batteries I don't care about. As long as I get a day and a half, at least, after a year, that's fine. Life is too short to be worrying about making you cell battery last 3 days longer than it should.

Big batteries, yes. You don't want any nasty surprises when Eskom wants more money has a breakdown.

Bought an Ellie's 1200w inverter which includes 2 batteries. Searched for an electrician and found one recommended by friends. He said he knows what to do. He put in an extra distribution box and related the plugs through there. First time I switched on the washing machine everything tripped and the inverter's alarm started. Anyway, to cut a long story short he had to come in and disconnect everything. He has so far charged me almost R5,500 to fix everything, so a major dispute going on.
Where do I find a reputable guy who knows inverters to install it?
