Please let me know if you think I've made any serious errors in my thinking.

 

Just did a test with one of my 6,000mAh cells which tested as almost exactly 6,000mAh at a 1A draw, when tested at 20A (the highest my tester will do) it tested again at pretty close to 6,000mAh. Cell was quite warm (no surprise) but otherwise happy.

 

Discharge rate, at least when sensible, has little effect upon available capacity. As to whether the life of the cell is reduced ...

      A quick and dirty response:-   500 units a month comes down to about 17 units a day, let's say 20 for round numbers. One "unit" is 1 kWh (kilowatt-hour).   Our panels make useful p

      Always best to over estimate and get a nice surprise, than to under estimate and get a less pleasant surprise.   A concept which seems to be constantly lost on my contractors when estimating

      I have 7.2 kw of solar panels, 750 Ah batteries and an 8 Kw inverter which is ample for my needs. I won't go into detail about my consumption but first you need to establish how much power you are goi

    The actual power output you take in from your panels depends on many factors. These factors include tilting and orientation of the panels, shading, season, time of the day, geographic location, etc.

    Not that hard, assume you'll get half the rated panel power for 6hrs/day and you won't be far wrong.

    330w panel x6 divide by 2 = 1000watts or 1 unit/day.
