G98 Certificate

[Mr Blobby]

I quite fancy the 8kW version of this newish hybrid inverter https://www.solisinverters.com/energy_storage_inverters10/5_10k_s6_H_PRO_en.html because it has, quite unusually, 4 MPPT trackers which is great for spreading across different sides of our roof. 

Yes I have 3-phase power and this inverter and battery will come in at half the price of a solar edge equivalent.

 

Before even thinking about buying this inverter, I wanted to check it is fully G98 compliant.

 

The inverter spec sheet lists the AC output as 12.2 Amp per phase and the spec sheet also states the inverter is G98 Compliant.

It isn't for sale anywhere in the UK but available online from various EU states.

 

The G98 certificate is not available online (AFAICS solis don't publish G98 certificates online) so I emailed SOLIS to ask them for the G98 certificate.

They are a bit useless. They first told me it was not G98 compliant because it is > 3.6kW.  Duh 🤦‍♀️

 

After explaing to SOLIS that the G98 limit is 16A per phase they said they'd look again.  They then came back and told me that ENA are awaiting assessment.  I had checked the ENA database before contacting SOLIS so I knew this already, but I thought that ENA don't do the G98 test, this is done by the manufacturer and then the manufacturere may send the certificate to ENA if they choose to do so. 

I thought ENA were just a library of information, not a testing and approval agency as such.

Here's the ENA page.....

 

 

Are solis fobbing me off here? 

The spec sheet for the inverter says it is G98 compliant so surely Solis would have a G98 certificate already, as otherwise that woul be a bit misrepresentationy? 

Am I correct in my understanding that it is Solis that test and issue the G98 certificate?

 

Would the G98 certificate normally be in the box with the inverter?

AFAIK if its not on the ENA database showing as compliant then it can't be connected to the grid under G98.

 

Type testing is the manufacturers responsibility and certainly for the Solaredge inverters I have its a third party that have done the testing and issued a certificate of compliance. When its compliant the ENA listing has a link which opens up the type test cert.

I finally got a copy of the G98 certificate for the whizz-bang 4-MPPT inverter I want to install. 😀

 

Solis have been good at replying to my support tickets and emailed me the certificate.  Its not on the ENA database yet but, AFAICS it is permitted to submit the G98 decleration with a copy of the G98 certificate even if it is not yet listed on the ENA database.  So if anybody wants it, just ask.

 

The problem for me now is of course that Northern Ireland have their own G98 NI certificate and NIE wont accept the GB version😫

 

I have asked Solis for the G98 NI certificate but am not hopeful.  The market is so small here that its hardly worth the effort for the manufacturers to be NI compliant.

I had my Solis 1.5kW Mini S6 Solar Inverter approved by DNO. Let me have your email If you want be to send the certification docs, they cover a wide range of units. May help.

To my surprise and delight, SOLIS have actually completed the G98 Northern Ireland tests for the new series 6 inverter that is unique in having 4 MPPTs. 

The G98 NI certificate is on the ENA website.  😀
