DNO - register for SoFar ME3000 charge controller and Pylontech Batteries

[marshman]

Link to a reasonable "tutorial" on the OVO forum regarding DNO permissions, "fast track" applications etc. Also mentions notifications required for Heat Pumps and EV chargers and the rational behind them.

Excellent summary. A few bits that are possibly misleading eg G100 isn’t just for east-west you can have an 8kWp due south array with 16A export limit if you want.

Apologies all but I thought I might attach my enquiry to this thread as its the same questions but DNO is Scottish Power.

Solis 5th Generation 3kW hybrid inverter and 4 off Pylontech US3000C batteries. Existing MCS system is 3.6kWp panels and Sunnyboy inverter, the batteries would be AC linked.

Having read all the other threads I am thinking that I am compliant with SP's guidance:

The fast track integrated microgeneration and storage procedure can be followed where all the following conditions apply:

The power generating modules are in a single installation.
The total aggregate capacity of the power generating modules (including electricity storage devices) is between 16 A and 32 A per phase.
The total aggregate capacity of the power generating modules that are electricity storage devices does not exceed 16 A per phase and the total aggregate capacity of the power generating modules that are non-electricity storage devices does not exceed 16 A per phase. If the total aggregated capacity of Electricity Storage and non-Electricity Storage devices is no greater than 16 A per phase, the single premises procedure described in EREC G98 applies.
All of the power generating modules (including electricity storage devices) are connected via EREC G98 fully type tested inverters.
An EREC G100 compliant export limitation scheme is present that limits the export from the Generator’s Installation to the Distribution Network to 16 A per phase. Engineering Recommendation G100 (2018) – Technical Guidance for Customer Export Limiting Schemes provides guidance on the connection of customer export limiting schemes (ELS) that operate in parallel with the Distribution Systems of licensed Distribution Network Operators (DNOs). You can find EREC G100 and its supporting EREC G100 appendices in our Resource library.
The power generating modules will not operate when there is a loss of mains situation.

Would others agree that I can apply via the fast track application or have I misinterpreted anything?

Hi Marshman,

I have the exact same bundle as you so its the same inverter, we had the electrician around today to quote me for the in roof solar array on the granny annex along with some battery storage there too, hes going to wire my set up for me at the same time (did I say I am practically lethal when it comes to wires?), in discussion we have moved the location from under the stairs (insufficient space) to an out building thats less than 5 meters from the consumer box so the CT clamp will be easily placed on the incoming grid supply. The out building has a small anti frost heater and good ventilation so the batteries should be kept cosy in winter and cool in summer

All I need to do is notify the DNO via their fast track route before he starts his work.

Thank you for the assistance it takes some of the worry out of getting these things right.

Hi again,

I have partly filled in the G99 form and sent off for review by the DNO.

They are replied asking me to 'Please can you advise on the load required.'

Will this be for the SoFar charger or for the SoFar Charger and the installed Sunny Boy Inverter - SB3600TL-21 and 16 solar panels Panasonic == 3.6KW?

Many thanks
JC

If you filled in the form correctly you would have said 3.6kW existing generation and 3kW proposed storage generation.

They might be asking whether you are requesting an increase in export from the existing 3.6kW or they are querying what your max house loading is in case you need to apply for a higher import connection which usually means uprating your cut out main fuse and / or your meter tails.

I would ask them to clarify what they mean.

Hi all,

I had a call with ENWL today regarding the addition of the battery storage inverter etc.

They are happy with the form now with the details of the existing and planned inverters listed.
To complete the application/notification they have requested a schematic for the install - existing plus new additions.
I have drawn this up and emailed it in.

All very straight forward, and ENWL very helpful too.

Many thanks to all with the help with this.

Hi again,

No received confirmation from the DNO that the application has been approved.

Thanks for the help and advice.......

Now thinking of adding another solar array probably an additional 3 or 4kw inverter.
Hopefully this will also be able to be approved by the DNO.
