I think you mean "capacity" for "capabilities". Capacity is part amount of sun, solar panel, battery, inverter, load and efficiencies. The load and how long it's on is the starting point.
You are right KIS, I'm sorry English is not my first language.
The load and how long it's on is the starting point.
I'm part of an Industrial Design team and we are proposing hypothetical scenarios for a mobile dental care unit.
The following are some of the loads (there are much more, but is just a sample to illustrate you the problem)
5 x Halogen lamp - 12V - 50W
5 x Electric Compressor - 120V - 920W
1 x Autoclave - 120V - 1000W (just a resistive load)
+ 5 x Small Computer - 120V - 100W
__________
= 2070 Watt running for 7 hours
Notes:
1) I noticed that the lamp cosumes 50W @ 12V, not 120V, so I would like to learn how to do the correct calculation
2) I didn't took in account the starting current of each motor, 225% during a couple of seconds according to a source.
3) I followed
bountyhunter's advice and learn about power factor. For complexity and time reasons, let's assume that PF is 1.
The problem:
1) I suggested the team to use 5500W diesel generators. But another member is proposing solar technology. I find her idea non practical for a mobile unit working on a country with very variable weather and topography. But in order to prove my point I should do all the calculations for the total power consumption, then compare the numbers with the (solar cell+battery+inverter) capacity under
ideal conditions (as RCinFLA noted)
If anyone can explain me how to do the above calculations correctly, I would be immensely grateful
PS: I understand all the concepts of capacity, Amperes / hour, C unit for charge and discharge, etc.
