    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...

    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...

    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...

    Low Voltage Light Question

    Hi all, Chum at work has 18 LV lights in the kitchen using the G4 5W halogen bulbs. Two bulbs failed but he could only get 10W replacements. Two questions 1. Will there be any detrimental affect having 2 of the 18 bulbs being 10W 2. If he replace all 18 bulbs with 10W, would this provide more...

    Using RCD tester on output of a dimmer

    We have a jobsite where the building owner insists on testing the RCD using a RCD tester on the output of the dimmer. RCD trips when dimmer is at full (100% conduction) but does not when dimmed down. I believ the tester is not designed to be connected to the output of a switch that is turning...
