    DNO turning off systemsDno turning off systems

    We fitted a 10kw system a few months ago, G59 approval was granted prior to installation and all was carried out correctly. unfortunatly there is high voltage in the area so the inverters were tripping at peak generation. We have recalibrated the inverters but still have a problem. so we have...

    Section 2.1.2 on DTI Guide - Voc/Isc mulitpliers

    Guys, As we know, for switches/cables/isolators etc, you need to multiply your Voc values by 1.15 and Isc values by 1.25 to calculate the relevant max values for suitable protection. However, does this apply to MPPT or Max DC voltage/current input values on inverters? Any thoughts? Thanks Andy

    6 used Moeller DS6 15kw Inverters for sale

    I have 6 used Moeller DS6 15kw Inverters for sale. They are in good working order being recently removed by myself from two enclosed panel boards. The site is two years' old so I imagine the drives are the same. I have looked on line for suitable places to sell these items but have drawn a...

    solar edge inverters

    Hi In the manual solar edge recommends using a type A RCD to 100ma. Is this what installers are using in the uk or is this some generic international statement? Does this mean that the solar edge is capable of leaking dc current onto the ac side?

    Android App for SMA Bluetooth Inverters

    I have been working in my spare time on an android app and thought I would share a screenshot. It provides a live view via Bluetooth connection, it works fine on my 4000TL and should work on all Bluetooth enabled SMA Inverters. It can also retrieve historic data from the inverter for the...

    Eltek Inverters

    It's honestly not intended to be a sales-oriented thread, more of an "info sharing" notification to make you all aware that Sibert Solar are now authorised distributors for the full range of Eltek inverters. If anyone has any interest then there's info on our website or feel free to contact me...

    Using Transformerless Inverters with Non-Grounded PV

    I'm trying to figure out if there is a way to implement a transformerless inverter on a non-grounded PV system. We are planning to install a 220KW PV system using Uni-Solar's PVL-128 laminates. Since the laminates are non-grounded, I've been told, a transformerless inverter will not work...

    small dual tracker inverters

    Does anyone know of a dual tracker inverter capable of splitting 1.25kwp west facing and 1kwp south? We have only used sma dual trackers on 4kwp systems before, and im sure sma dont do a small sysyem dual tracker inverter. We wanted to avoid using/quoting for 2 inverters for cost reasons if...

    Outdoor Inverters

    We have installed a few outdoor inverters in the last 6 months, just wondering if anyone has photos of any that have been out in the elements for a year or more, interested to see how they hold up to hot/cold/damp/wet/UV exposure etc...

    2 SB 3800 Inverters, 9600 kwp array, one 60m export cable. Inverter cutting out?

    I have a recurant problem on a system which one inverter gets a AC fault. This happens alternately, either one inverter or the other. The fault seems to be at peak output but does not trip any breakers. The system is very wrong in the fact its all on the one phase (as only one available), but...

    Combining two SMA SB1200TL inverters in a system design?

    My boss who designs all our systems has had me construct AC work consisting of two SMA 1200TL inverters combined. Meaning, own circuit until the finally meet at the 3 phase meter terminals. I personally thought this was incorrect and they should be totally independant of each other until the...

    Undersizing Inverters

    Sorry to bring this up again. I know it's common practice to under size inverters I.e 3.6 Inverter in 4KW of panels. But has anyone got any technical reason (and not a computer simulations) why this is fine. I've always been told it is fine, but never 100% convinced (the "we don't have that...

    Ecobuild - cheap panels?

    I was just wondering if anyone saw any good deals for panels on their travels at the event? Cheapest we heard was from TD Solar. I couldn't get much info from him as there was a bit of a communication barrier (My Chinese is notoriously patchy) but his cheapest panels were down at 53p a watt...

    Locating of inverters

    I've been to look at a potentially large job this morning (gasp) and locating of inverters has been thrown up as a problem. There is plenty of wall space - it's just out of reach. I was wondering what the general opinion was on locating the isolators at a lower level and then mounting the...
