    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...

    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...

    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...

    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.

    Need help for PWM circuit!!

    Hi guys, Will like to seek your help. I have a 5V pwm controller/generator. This signal is output by a MOSFET. I will like to use this generator to execute PWM (15kHz) on a battery which has a high voltage of 40V. I believe i will need to connect this controller to probably another IGBT, which...

    3 phase converter

    Hi guys I've been given a 3 phase converter to fix made by Motorun Phase Converters Teddington whom I can't seem to get in touch with.I've fixed the initial fault which was taking out the RCD because neutral & earth had been wired together on the outlet plug.This converter seems to be a hybrid...

    LED GU10s

    Recently I keep getting asked about LED GU10s, and I don't know if they are any good, I have heard they aren't, but don't really know enough to recommend or not. If I were to swap 8 x 50W GU10s with the LED equivalent would they be as bright, and how long do they last? and is the quality of...

    how to convert from rotation of dc motor to output voltage

    how can I change the rotation of the dc motor to the voltage? for example, when the dc motor is connected to the light, the light will light up. so my question, how can I get the output voltage on screen when dc motor rotates.?
