    Can Solar panels cause tripping when isolated

    Anyone know if its possible for a rooftop solar array to cause an RCD trip even when the solar circuit is isolated at its rotary isolator ? I've had no dealings with solar atall so wouldn't know . The solar circuit is in a split load RCD board. I'm assuming the solar install was bonafide as its...

    Good afternoon from an overcast Mullion Cove. I am a retired Radio TV radio telephone engineer.

    I spend a lot of time renovating vintage broadcast radios, military radio and test equipment. At present adding panels to our off grid installation. The balcony railings are now full of panels : ) so the state roof is next. Alanna and I replace the flat roof with EPDM and re-slated the remains...

    Low Amperage From 4-100w Renogy Panels

    Hello all. I had 4 renogy 100w panels running to a 30amp renogy charge controller. I started noticing a low battery situation so I started doing some tests. If I completely disconnect the panels from the system and check each panel individually I get between 19.5-20.5v on all 4 panels, but I am...

    Solar Panels Can I add solar panels to an existing system without losing my fits

    Can I add solar panels to an existing system without jeopardising my feed in tariff? I have a 3.8kw system but was thinking of adding a few more. Could I have 6kw of solar but limit the inverter to 3.8kw so it will help in the winter when I need it the most. Or would I need a second meter to...

    How to install rigid conduit between two surface mounted panels?

    I need to re-route some circuits from one surface mount panel to another. There is a 4” gap between the two. I want to use 1” PVC or EMT. Because of the limited space, I am looking for suggestions for a legal, secure method.

    Surge protection for Solar panels...

    Hi, I have recently had 18 solar panels (390W) fitted to my roof. The system is a GivEnergy. A Gen 1 Hybrid 5kW inverter (Gen2 version could not be sourced!) and a 9.5kWh battery. It all works well (although not much use with just winter sunshine). My question is: I'm sure I have read that to...

    Color code for wiring

    We have UL 508A for US and C22.2 No. 286 and No.14 code books for Canada. I have seen TEW, THHN wires etc., being used for wiring inside the panel. We have 480V 3 phase and other derived single phase voltages from transformer like 208/120 and 24VDC. We have been using Black TEW for all high AC...

    difference between semi flush and flush service panels?

    I am upgrading an old 100A semi flush outdoor overhead panel to 200A solar ready, panel. Was looking at Square D SC2040M200PF, but this appears to be designed for bottom feed- with option for top feed. Does not appear ideal, and my installer says might be a real PITA. I am not seeing many...

    Any best practices on installing/wiring configuration of multiple LED panels?

    Anyone could recommend "best practices" for wiring methodology of 64 LEDs (each req. 10V@700mA)? Including resistors, drivers, parallel/series, etc... Part of the question is if these should be configured in an 8 x 8 configuration where each one bundle is a 4 x 4 series/parallel setup? Drivers...

Basically roughed in a new build for someone, was told he was haggling with the local authority over the price for putting power to his house, it's in the countryside.

    Will replacement panels of same total capacity jeopardise FiT payments

    Hi all, as per the above title. If one is to replace the existing solar pv panels for a new system of equal capacity (existing system is 8 x 250w=2000w total) with 5 x 400w=2000w in total, will that risk jeopardising FiT payments. By doing that it would give enough room to add 4 more panels of...

    Solar Panels How many panels on this space?

    So I've looked at the dimensions of certain panels and they vary depending on cells but whenever I speak to a company about how many panels I can fit on my roof they always reduce it down to the point where I'm wondering is there some sort of rule about how close to the edge of your roof or...
