Do I need MCS etc?

[uksparks]

Hi,

i cant really go into it to much as a bit top secret, but am going into something with someone who has developed something where it needs an Inveryer connecting up that's grid tied a G83 etc so it cuts off and what not etc and so on la de da, anyway, so he wants me took hook this Inverter up but do t know if I need to be registered with mcs or someone as I'm connecting up a 230v supply to the grid, it's not "directly" from PV or wind etc, feed in tariffs etc do not enter in to it.

any ideas?

I'll e plain that better, we have a bank of batteries that are connected to an Inverter basically. Can I just hook this up or do I need to be registered with anyone or tell anyone?

I would have thought the DNO will want to know about it!

 

[uksparks]

Yes I was thinking that but don't really know where to start and wondered if someone could enlighten me as to what I may have to do.

Presumably I can fiddle around with DC and batteries and inverters etc? It's not something I've touched before, it's a new one on me.

What's the KW?

 

[uksparks]

6kWh, that's the small one, the big ones go up to about 65kWh

Then it needs approval before hand from the DNO and won't be covered by g83

Generally no, but you will need to send a connection to connect application to the DNO, they will want to know how you are able to ensure it meets all standars required, this is usually where we put .MCS registered'
Call the DNO and see if they are happy with just the application, as long as you have the test cert G83/2 for the inverter they should be happy with that.

If you're generating and feeding the network, I'd of thought the DNO would want to know.

It's in prototype stage at the moment and am hooking it up next week but not to the grid, i just don't want to hook something up to the grid with fully 100% understand what I can and cannot do and what's allowed. It's not micro generation as its from stored power.

Sounds like someone has Re-Invented U.P.S

 

[uksparks]

It's through a proper inverter and all batteries CE and IEC certified etc.

Mots kind of like UPS but it's not as a UPS only supports the load side, where as this is like an inverter connected to ZpV but works in the dark.

if you got battery storage then hook up some circuits (lighting etc) and not bother to sell back to the grid. (they dont pay very well anyway).
use a double pole change over switches between grid and inverter output.
edit: immersion tank heater is anoter good way of dealing with excess of power daytime and having hot water in the evening...

I've hooked up a set of batteries to be fed from PV to the grid. All loads primarily come from the batteries and the gird picks up the slack, any excess gets exported. It's all covered by a changeover to keep the loads running in case of gird failure, capacity dependant of course.

DNO just need to know capacity of system and a wiring diagram if you're going to be exporting. Just let them know within 30 days of commissioning. As for needing to be MCS accredited... I'd say you'd become a sub contractor by definition and if I remember right you don't need to be. It spells it out clear as mud in the MCS regulations.
