Samil 3300TL

[infinity]

Has anyone used these inverters? pricing a job tight and they are relatively cheap with 10yr warranty which seems good!

Never used one but intend to - heard good things about them. As an aside, has anyone used the twin MPP versions, the TL-D's? There's a couple of sub-16A output versions but they don't seem to come with G83 certs, only G59. Are DNO's OK with this?

we've installed a few now, and as far as I can tell they seem ok, had a decent review in Proton magazine a bit back that convinced me they were worth giving a try on our value range.

One point to note with them is that they don't guarantee the level of DC input to the grid / earth leakage in the same way that SMA, Aurora etc do, so IMO shouldn't be used on shared RCD's, or any standard RCD not designed specifically to cope with DC currents - sorry, Friday afternoon so someone else will have to do the type B, C thing as my head isn't finding that info right now.

THey also don't have any shading function similar to the SMA optitrac global peak, so we generally only use them in unshaded situations, unless the customer really doesn't care and just wants the cheapest thing possible.

Thanks for the info.
Well of they can inject dc into the AC then it requires the expensive £300+ type B rcd protection which blows the value out the water!
You can buy SMA TL's instead of spending out on the extra. So you install a B Type rcd when you have used these?

Cheap cheap
May i ask what kind of car you drive Infinity

nope, we've not used an RCD at all, we'll usually be running it either clipped direct or in SWA anyway, and just use a double pole 16 amp MCB (which are available if you look hard enough) fed in to a tails block.

I reckon this is where virtually all the issues are happening though with cheap arsed installers installing these to shared RCDs, then a spark comes along later to test the RCD and finds it sticking.

yeah, but that's not a Samil.

We've got one in the warehouse, I wonder if I can be bothered to open it up for a photo.

We fit samil very good and no problems yet

 

[Gavin A]

sod it, I'll see if I can get a photo of the inside of one of them, unless it's reet cold in which case I'm going straight home.

BMW & a Freelander why?

The price of the Samil is pretty appealing thats why i was looking.

Thanks for the pic Sedgy, im going to give it a try, all looks good to me.

Why not the Steca, that would be my choice. German quality.

we use them as well and are pretty impressed, but the voltage range on them is too high for a lot of jobs smaller than about 14 panels if using the standard 30V panels.
