250watt Grid Tie Inverter

[philipaharris]

Hello,

I am interested in doing a small pet project using the 250watt grid tie inverter that I have seen on here in the past.
I have a couple of questions.

Is it still available, because I can't find it in the shop area anywhere?
I know the unit is not G83 certifed. Is this garranteed to be ok, legal etc and not breaking any rules?

thanks in advance,

We have not got any in stock currently. Best suggestion would be to give the office a call in about 4-6weeks - they should be able to let you know when they will be due back in

Thanks Ivan,

What about the G83 issue. Are these units definately ok to use without the G83 certification?

thanks,

I would place that question with Ofgen - they decide, at the end of the day. I spoke to them about 2years ago, and they told me that G83 was not a legal requirement (it cannot be, until it becomes a standard. At the moment it is only a recommendation), so it is not necessary, but that you won't find a utility company that will buy the electricity unless it is fed by a G83 compliant unit. There are other standards (BS standards for example) that deal with the unit disconnecting within a certain time period after grid failure and so on, and the unit complies with a whole bunch of these - but you will need to check with Ofgen for the latest position, as rules and regulations seem to change very regularly, so it may be different now.

Is there any prices on the inverter yet?

I spoke to Navitron this week about inverters. They recommend Sunny Boy; they don't stock them but can do a good deal on price.

They are a bit pricey, the minimum is 700 Watts peak, but they look rock solid and well designed.
