It has been pointed out to me that grid-tie inverters are 'all or done' i.e. on at 95% efficient or off.
I ponder that if less output is desired why the mppt optimization can't be severely skewed to accomplish such. We know that the logic is to shift the dc loading or the panels such that the...
It would really be a shame if Florida got hit with another big hurricane and we had days (or weeks) without power and had to look at perfectly good panels, glistening in the sun after the storm, with no output whatsoever because the grid was down.
I don't want to offend anyone, but I was hoping...
Really looking to migrate to a 'no generator' plan.
Thinking about a couple of kw 240v inverter from a battery bank. The last post is the way to manage quick load changes. Another variation is a current control on a battery charger to the batt bank where the charger current is regulated to...
Proposed Project Purpose:
to utilize solar energy during a utility power outage
The Situation:
isolate house, run on off-grid inverter or generator, tie with solar inverter and load managed variable dummy load.
solar inverter being and on or off device can pass more energy at any given...
I just talked with an oriental sounding engineer at SMA about Sunny Boy. He said that grid-tie devices have the ability to burn out a generator and that there is no current limiting in the 8,9, or 10 kW units. If the line and freq stays within specs, the inverter will max out the current it...
Looking to build and install a 10kW solar grid-tie system. Normal operation will be with local utility grid attached. When utility is down ....
Already have a 24kw diesel generator on-site and want to be able to get the solar to sync with generator. Need to find the inverter designed to...
