I want to run computer equipment - around 2000 W with another 2000 on the way in a few months. What would you suggest for the backup power? My priorities in order of most important to least important are:
1) Surge protection
2) Buffer from brownouts and general fluctuations
3) Ability to run while power is down (1-3 hours)
4) Ability to connect solar at a later point.
For 1) should I just get surge protection at the DB? I also need it at the Cat5 cable since it routes outside / underground.
Would it be better to get an Inverter + MPPT charge controller + Batteries for now (charge controller connected to Eskom) or should I consider a UPS? Which is more efficient? Is the charge controller a waste without the panels? Cost wise I imagine the charge controller + inverter + batteries rivals a good pure sinewave online UPS.
I'm thinking 6kva min.
