Inverter noisy - what other options would you suggest?

moggy1968 · Mar 20, 2012

have sent you the user manual. if you need anything else just let me know.

YOZ - I've not used the 3000Tl, tend to use the 3000HF but unless there is a need for an RCD under 17th ed there is no need for an RCD, on this or the 4000TL. I don't think 2 strings would be needed. Why did you think it would be? I haven't checked the inverter stats but would have thought input voltage would be fine on a single string.
4mm cable is fine unless the AC run is long (over about 20m. if it's close to that let me know and I'll do the actual calcs). I'm pretty sure the manual says you can also use 4mm on the 4000TL dependent on the length of the run, but it doesn't give you much length.
The original poster is the customer and they've got what they've been supplied with, a 3000TL

Thanks received it, and have replied with a question ;-)

For info the 12 panels are in two strings of 6.

okay, are they in 2 strings because of different orientations or shading issues or do they have fairly consistent sunlight accross the whole system? If so they can be wired into a single MPPT inverter no problem assumiong the start up voltage is low enough. If not you need a dual MPPT inverter (I believe the power one 3000OUTD has this, but I've never used one). I would say SMA monitoring is better though IMHO. I've used the power one 3.6 and the monitoring isn't great.

They're all on the same roof and although it has some tree shading that moves across this is only a factor in the (2) months when the sun is very low.
The Schuco 3000TL has two string inputs, as did the original Sunmaster XS3000, so I've assumed that's OK.

Did you get my email? - my ISP 1&1 has had their mailservers tagged as SPAM sources so lots of emails going into recipients webmail junk folders before reaching their Outlook etc :-(

yep, 2 string inputs but only one tracker.
doesn't sound like a major drama in your case.
Looking at the minimum voltage input you'll be fine on the 2 strings
got your email thanks, I would say if this is a rebranded SMA inverter you will be fine with software and bluetooth etc. It's just the colour and name on the box thats different.
