Yes, but as mentioned, some people say because its modified sine wave, it will damage electronics. I can only speak about my own experiences. My mom regularly has week long (at least once a month) power outages where she has a 10KVA modified sine wave generator running the whole house. For the past 9 years of using the generator, not a single electronic device has broken, including LED TV's and PC board fridges.
A lot of the inverters the guys use are modified sine wave and they'll plug their TV's into that.
Most them use mecer it's pretty good modified sinewave. Generators voltage can be pretty wild at times
Not seen voltages fluctuate that much on the ones I've been using, in fact I've seen Eskom go from 220 to 238 in minutes, where as my generator sits at 220 to 222, can't really think of a reason the voltage would spike much higher, but dropping when petrol runs out of course, but it's generally as quick as a power failure. But plug in surge protectors before the item you're using it with? Like should be done now anyway.
Never plugged the mecer into the genny :-( and can't at the moment until payday and new battery.
The frequency is critical. MUST always be 50 Hz. My generator loads up ( say, with the geyser when I had an electric one), and the Hz goes to 48 or so, the Mecer inverter would switch over to battery - doesn't like it one bit. Also fridge starts making nasty noises.
Modified sine or squarewave has no effect on modern electronics (tv computer etc) which is why it is used for computer backup UPS's. What can be damaged is inductive loads such as microwave transformers, fridge motors and older battery chargers with transformer power supplies etc. These usually are noisy to warn you and they will also be overheated.
During one power outage I ran my computer directly from 20 ups batteries which is DC 240Volts. It works fine except the old VGA crt screen I used became magnetized and so the colours were green and purple but the degaus circuit fixed that immediately when Eskom power was working again.
You ran your computer directly from a 240V DC source?
Nationally it's stage 2 until sunday 23:00. So cape town will be stage 2 otherwise stage 1 when they can. That's how I interpret it.
The hydrodam needs time to pump the water back up. This is normally done during the quietest time.
You can actually. Almost all computers use switch mode power supplies; the very first stage in any SMPS is a rectifier circuit that converts the 240V AC mains into a DC voltage (which is higher than 240VDC by the way).
He is a very brave guy.
A pc power supply is actually an ac to dc inverter.
Really?
Europe having grid issues
Slightly off topic, but interesting non-the-less; Yep, the grid frequency deviation has a nuisance effect, but implies deep underlying issues.mybroadband.co.za
