    Low system output during indian summer?

    Hi Guys, Anyone else noticing systems not reaching very high power outputs during the last week of sunny weather? Any if so any idea why? I'm an installer, not a system designer, so maybe there is an obvious answer to this that I am missing? We commissioned 12 systems on thurs and fri last...

    Expected max output?

    Hi all, I have just had 8 x 250w Hyundai panels & SB1700 on asingle sting installed. my question is what should I expect the maximum out putto be? Today the most recorded is 1198w.

    Upper voltage shut down

    Hi I read on an old thread from BruceB that voltage drop should be added to the local mains voltage to find out what the voltage will be at the output terminals of the inverter. I have a situation on a 50kw system with 3 X SMA 15000TL where 2 work fine however the 3rd is generating a lot less...

    Generator problem/question

    Hello Electricians here. I have a Prob/question and am hoping that someone can shed some light over here. I have a small portable generator driven by a petrol engine. 2 outputs = 220v and 110v But the generator will not generate, I have checked the wiring I can and all switches seem ok ...

    using garage roller shutter lighting output on a 2-way light circuit, relay?

    bit of dilemmna with a customer. hes had a roller shutter garage door fitted, it has a 40w output for lighting. the thing is the garage has x4 5ft single fluros fitted on 2 way switcing from house door and near garage door (largish garage). he wants to the lights to be functioning from the...

    One string suddenly seems to have reduced output

    On my newly commissioned system - 16x Sanyo HIT240 and SMA 4000TL - all has been going well, even to the extent of seeing over 4kW on the inverter dispay a couple of times yesterday and this morning. This afternoon, in good sunlight, I notice one of the strings will never get above 1.8A (about...

    Very low solar panel output

    Hi guys, this is the first time i am doing a solar charger thus will need some help. I did a simple check on the solar panel. I tested its open circuit voltage, which is around 7-6V depending on the light. However, when i connect it to a 200ohm resistor and a normal LED, the voltage across the...

    Octava hdmi matrix switch

    Anyone come across an octava 8 output hdmi switchMy bro has one and has had a James hunt of a job trying to get it to workIt outputs hdmi signals down cat 6 cables with an IR blaster at the tvI think you can output from 4x hdmi sourcesSometimes the tv goes green with no sound and other times it...

    What size are you quoting on DNO forms - Peak or Instantaneous output?

    Had a meeting with One of the northern DNO's today and they were as helpful as ever, we were actually talking about over 50kw but this question also applies to the 3.68 to 4kw range. On the ENA DNO application form it asks for the net plant size - what are you filling in for this figure? as I...

    How often should peak output be hit?

    Hi Ok, I know that temperature makes a difference but I've got a customer 'commenting' that the 3.36kWp system I put in hasn't hit 3kW yet. I was wondering if anyone had any indicators whether I should be concerned or not. All commissioning tests proved OK etc. We've had a few good days...

    honeywell s plan programmer & glow worm boiler argghhhhhh

    Can some one advise me on a problem im having with this heating system. Ive wired the programmer exactly how the instrustions said. it exactly like this diagram S-Plan the thing i dont understand is the boiler has a seperate output which is L-N-E to the pump Then L-N-E & R(switched...

    Average Annual Power Output per pound spent vs Panel Efficiency

    I am in the process of getting quotes for a PV system of up to 4kW for a house located 35 miles SW of London, and have been looking at various manufacturer's claims w.r.t. performance. The primary data that I seeing presented are: maximum panel output panel efficiency, albeit no satisfactory...

    LED light vs fluorescent

    I have an LED T8 tube, 1.2m, on 240VAC it draws about 80mA and should have 18W. I do have compared it with a 1.2m fluorescent T8 tube, 36W plus ballast which has on 240 VAC 400mA. The current I have measured with an AC multimeter. Means the LED light saves 5 times the power. If I compare the 18W...

    5 year product warranty - 25 year performance warranty: confused!!

    Can anyone help me work this out? Most panels have a 5 year warranty on the panel yet have a 25 year warranty on the performance of the panel. Isn't this a bit odd? Surely if the panel malfunctions, then the performance will also be affected. Therefore, haven't they all effectively got a 25...

    DNOs and G83 limit

    Guys, can I ask you all to reply to this thread with details for each DNO that you have had dealings with and their approach regarding the G83 16A limit - plus any info if you have seen that this has changed over time. The ENA have confirmed that the correct value to use for the G83 limit is...

    Output voltage of this setup?

    This is probably really simple for you. I don't really know where to post this question. I only have two questions. What would happen? What would the voltage be? Envy my mad mspaint skillz. What I'm after is a setup that supplies 18V to my active guitar pickup and probably 1.5V for the...

    10000TL inverter - 3 phase output and number of strings

    Does anyone have any experience of the SMA 10000TL inverter? I was wondering whether the number of strings had an effect on the 3 phase output of the inverter. For example, does the array need to be arranged as 3 seperate strings?

    16A threshold for G83 - Array size or inverter output?

    The saga continues. I was told today by an engineer at Central Networks that it is inverter output that is important when considering the G83 threshold. Hopefully this will be the stance all DNOs take before long.
