SB 4000TL - excess power

[edexlab]

But see again the wording on SMA's G83/1 certificate for the 4000TL

I think any unit intended for UK distribution should be preset at the factory and then Grid Guard set so that you can twirl the knobs any way you like but they won't alter the G83/1 settings. If moving your knobs is changing the parameters (without password use) I think it indicates that the unit was not preset at the factory for UK use, which is perhaps supported by the lack of an english manual in the box. I think the 5 8 setting will set it to G83/1 but not with Grid Guard set, ie not tamper proof as a factory preset UK unit would be, which means strictly it would not satisfy your DNO's request.

we've had several inverters now all have a separate form stating the inverter must be set via dials to conform with G83
follow the instructions and when commisioned the country setting comes up as G83 on display
I know that if they are ordered for uk they are factory set
but Sma are bound to sell inverters in bulk (with unknown destinations) to wholesalers covering more than one country who can either set the inverters to a country code or sell them and let the installer do it manually ,

I'll check again but after commissioning does'nt grid guard protect settings after a few hours

There is a 10hr 'burn in' period, after which the country setting is locked, and can no longer be set via the dials.

If you buy your inverters from a good source (hint hint) then they will all come as G83 UK spec.

thanks for that I'll have a look at your site

I take it that when you get them you'll set them or is it a case of you're only buying for Uk and so its done by SMA

Also what makes you a good source compared to others? , most wholesalers are like the installers fairly new to this market with the exception of companies like wind & sun who are extremely knowledgeable

@Ken... This one came from a big supplier who had some conferences recently... They do actually state on their website that some of their inverters will be european of origin and of installation manual...

As for a 'good source' i had a nice chat with one of your people this week and am awaiting my emailed price lists etc (hint hint).

As long as you set the dials within the first hour of operation of the inverter it will set to UK settings thereafter the dials become useless as the Grid Guard settings become fixed and cannot be changed.
They can be changed thereafter only with bluetooth laptop connection, Personal Grid guard code and SMA software. The Grid guard code is unique to the installer and therefore any modification carried out is traceable by the DNO back to the installer. Hence the Grid guard settings are protected from tampering.

If you receive a european set up Inverter normally 00 then you will need to set it to UK g83-1 which you can with the dials. but if it has been run for 1 hour without setting the G83-1 parameter then you will not be able to change the settings without a Grid Guard Code.
