    UPS specification for pool pumps

    FWIW. I manage a site with pool pumps etc etc. If grid is lost, there is a 20 second delay before genny powers up. UPS's are used for the internet and internal comms to enable reporting of what is going on. Because the genny is not powerful enough to power all possible loads, certain loads are...

    Day 1: Who has an Electric Vehicle, either Electric Car for home, or Electric Van for Work?

    Bought a damaged Cat S Leaf, 12 months old 2400mls, threw some body panels at it and been driving it for 12 months now, done 12500mls. Its my primary vehicle but still have the big BMW Estate when i need to carry the kitchen sink on a job. Fuel costs down by 2/3rds ish as i can charge at clients...

    Notify DNO of air conditioner installation

    Looking at the size of them, i think 14KW refers to cooling capacity not electricity load

    UK Safe isolation

    Thats not how it works. You have identified a need to switch power on and off for testing purposes. You have decided for the minimal movement of Cherry Picker ( a risk in itself) to use a remote method using a second electrician to co-ordinate such switching. To minimise risk for the chance the...

    UK Safe isolation

    Hope so as i use this technique often. You can always check the live ends before touching them just in case the 2 electricians get out of sync. Good comms is vital to your sanity as i have found "off" and "on" to sound similar, in an industrial / noisy environment. IMHO in this scenario it is...

    Is there a switch which works as per a high beam?

    There are loads out there , who knows what would work, lol - I just use a button on the steering wheel - if the headlights are already on, one press puts on high beam, press again and it reverts to low beam. If headlights are not on press once to flash. I dont use any stalks as they can get in...

    Is there a switch which works as per a high beam?

    There is the option of changing the existing stalk for one that also has forward and back to operate the high beam. That used to be the way for many older cars. Then use the stalk to operate a relay for high beam as typically these stalks do not have the umph to operate the lights directly.

    Almost qualified, but low on confidence

    I really dont believe your age is even remotely an issue, over 60 for me now and quite honestly i am not as fast at a particular task BUT i make less errors now that would require duplicate work. So overall i am probably as fast as i was 10 years ago. I work at a slower pace, have frequent...

    Gripper sensor

    Is the issue, that the plunger switch does not return to the off state because it is stuck ? If so there are a couple of ways to solve this, either by the PLC detecting the off-state (i.e. because it is not in the on-state), this can be done a number of ways depending on plc type and programmer...

    Best way to maximise export of generated electricity?

    Not sure what you are trying to achieve, first question says best way to maximise export, second question is best use of 8KW of panels, which one is it ? As obviously using the panels for self consumption is the best.

    Help understanding little solar production

    If the batteries are charged and the house is taking little then the full production of the panels will be dumped into the grid. As you have set it to no export on the inverter, then your solar production is reduced massively. Suggest put the kettle on and see if the production increases

    Help on solar planning

    Need to crack on to get most from this year :cool: BTW if you are thinking about adding to the strings later, i.e. add more panels to existing string, you will get a better output if they are all the same make, model, power. I know from past, that panels are changing all the time, a year is a...

    Help on solar planning

    Wish i could do it for my own home, sadly my roof is hopeless for solar. :-( I worked out, doing it myself, it would pay back in 3 years, which is half the time most people have to wait.

    Fuel Gauge needle moving with revs issue

    There does appear to be an issue with the diagram as the fuel gauge looks to be fed by AC, as i think (its hard to tell and someone has used a highlighter on it which makes it difficult to check colours BUT a regulator/rectifer is much more useful than separate items for sure. It sounds like...
