Can anyone advise me on which application i need to make please, UK Power Networks werent particularly helpful when i said i wanted to submit my own application, I was told i MUST use an MCIS qualified installer. When i challenged her and told hew i would be using a competent and fully qualified electrician for the installation, she didnt seem best pleased for some reason? Anyway, the electrician i am going to use (who we use for all our electrical work) has no experience in submitting the forms, so i said i would do them. To explain what i have and intend to have is this, i already have a 4kw PV system installed under the FiT scheme and MCIS installed, so i am not looking to ammend that in any way and potentially impact or lose those payments. i am looking to install an 5KW ECCO Sunsynk hybrid inverter and 28.6kw of battery storage ( 2 x 14.3 Seplos 280 L upright cases from Fogstar) that i can charge during the off peak rates 0030-00430 in the winter and the solar in summer. we are all electric and have Dimplex Quantum storage heaters. i have spoken to Sunsynk and the inverter is suitable for my setup and will be set to zero export to the grid and will get close to fully charging my batteries overnight. The inverter is on the approved list. My question and the help needed are as follows 1 Am i right in saying i can use a competent and qualified electrician rather then MUST use an MCIS registered installer? 2 As my 'add on' system will not feed back into the grid, is it a G99 application or a G98 notification i would need? i suspect its a G99 as its more than 3.68kw, assuming that refers to the inverter NOT the storage, albeit it wont be feeding back to the grid. My confusion is with the term micro generator - the inverter isnt a generator (is it?) and neither are the batteries?. The only generator are my PV panels and inverter already installed, or is this just a 'catch all term'. if anyone can offer any advice on completing the correct paperwork, or which parts i need to complete (Part 4?) then that would be extremely helpful, even better if someone could share their application made under similar circumstances. i'm not trying to fight a crusade but i get irritated when i am told i cant use a competent, qualified electrician to install electrical equipment - it reminds me of the old CORGI regime who turned their scheme into their very own thiefdom ......

Morning everyone. I'm a retired fireman who served his plumbing apprenticeship prior to joining fire brigade. We have a small portfolio of rental properties that I've renovated before letting them out, so I've got a few additional skill sets and experiences along the way. Old dogs can learn new tricks ....
