Hi All,
Had a PV system installed today - 16 x 250w Sanyo panels (have had DNO permission to go over 3.68kw) and a SMA SB4000TL, so what settings should the inverter be set at - the installer has set it at 0 and 1 - but I have read somewhere that it should be set at 5 and 8, is that correct?
In...

It has twin 250w drive motors, brand new (year old) 33ah battery goes for miles. It is remote control but i have never had a remote for it.

how can i find out the engineer code for this alarm system ( already fitted when i bought the house). i need to reprogram some of the settings and the user code does not work for programming. the default engineer factory code..1234 has clearly been changed so also does not work, or do i need an...
Guys (n' girls of course)
I have just started using a 1653B FLUKE and when testing earth loop impedance Ze (ie. impedance of supply - tested at supply origin), I presume I use the 'LOOP IMPEDANCE' setting (line to protective Earth L-PE) using the Z1 Hi current setting, and NOT the 'Earth...

Just wondering what protection settings you have been including for displaying next to the inverter. I've looked at the DTI guide but i'm not too sure what to put from the inverter manual.
Any help would be much appreicated.
Thanks, Mark.
Hi
I must be having a senior moment here, but I'm trying to find the protection settings for my SunnyBoy 3000HF. I can't seem to find it in the manual or datasheet.
Can anyone point me in the right direction?
Thanks in advance!
Trying to google a product that can do this - but struggling to describe it!
Has anyone come across a switch that allows lights to be fully on in one position, very low - for night time use in a second position - and completely off in a third - and without resorting to a preset dimmer...
Hi all,
In our DNO notification form it asks for confirmation that, for the inverter:
"Protection settings have been set to comply with Engineering Recommendation G83/1."
&
"The protection settings are protected from alteration.(except by prior written agreement between the DNO and the...
Hello All
I am looking for peoples experience of using small PLC's or Logic Relays in the domestic setting. I am looking at the likes of the moeller easy, mitsubishi alpha, and the likes. I have only used one of these types of relay in an industrial application over ten years ago and this was...
Hi,
A puzzling issue today.
When I test for Ze and Zs on my Fluke I tend to go for the 'no trip' setting out of habit. I believe whether there's a RCD or not this test might take a little longer to get the reading (as it saturates the RCD with a DC current) but it's the same result as the...
Anyone know the setings for a serial printer when used with a megger cm500 MFT? Baud rate,stop bits,parity etc.
Cant find the info anywhere.... the handbook just mentions An " appropriate" printer.:confused:
