aissecur Posted January 4, 2018 Share Posted January 4, 2018 When you next visit maybe worth taking your multimeter to ensure all the voltages the panel is outputting are correct & within tolerance.. If you have a phone line at the property I seem to think you can remote dial into the panel (Like you can on the 595 / 600 panels), that may help you get a better understanding if your such a log distance away Quote Link to comment Share on other sites More sharing options...

PeterJames Posted January 10, 2018 Share Posted January 10, 2018 Just another point I would not recommend installing a battery bigger than 3.4Ah the PSU is only about 1amp the current draw on a flat 7Ah will knacker the psu Quote Link to comment Share on other sites More sharing options...

The battery is the biggest I could squeeze in, bigger than the original. When you say knacker the PSU, what do you mean? Wouldn't a PSU either 'work or not work' and if it's not working, then the battery would be completely dead by now wouldn't it? Quote Link to comment Share on other sites More sharing options...
james.wilson Posted January 11, 2018 Share Posted January 11, 2018 A flat 7 Ah will want more power to recharge than the psu can provide unless very lightly loaded Quote securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

PeterJames Posted January 11, 2018 Share Posted January 11, 2018 As James says a flat 7Ah will draw more power than the PSU is designed to supply, therefore putting unnecessary strain on the transformer, eventually wearing it out. Its like using a Nissan Micra (Your PSU) to tow a fully loaded truck up a hill (Your battery) People often think that bigger is better without taking into account that the current required to charge it when its fully discharged. 1 Quote Link to comment Share on other sites More sharing options...

I see what you are saying but will a transformer 'wear out'? I can understand how it may get hotter than it should if it's under too much load but it will carry on working as it should until it eventually burns out, and stops working. Won't it?

What Bout the charging circuit? What's your point? Any component overloaded will drop it's output and heat , so how is that working ?

Won't it? the tx will survive the charger wont, have a look at the bored(sic) Its designed for an assumed load, You cannot expect a budget pro panel to take a proper load. Also yes a tx will wear out, if you overload it, they have a design temp and load Quote securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

james.wilson Posted January 11, 2018 Share Posted January 11, 2018 it will melt the varnish of the windings, but id assume the reg will fail first, taking the br with it, then the tx ideally that will cause an mcb trip, but if your on rewireable fuses who knows.
