    UPS | Extending the backup run-time of a UPS with an external deep-cycle battery.

    Roughly calculated, but will decrease to stick within that load: 4 LED outside perimeter lights 10w each. LED lights for 3 rooms Burglar alarm Server Modem/router 24 port POE switch with couple IP cams CCTV DVR TV with PC

    Thank you kindly for your time Geoff :notworthy: I'm giving up on this and tossing the idea, will explore the inverter route as with @Dairyfarmer's project.

    UPS | Extending the backup run-time of a UPS with an external deep-cycle battery.

    Thanks :thumbsup: That explains @Chuckmyster removing his batteries too and replacing with new larger ones. Cost of replacing all batteries with new big ones on the UPS vs inverter setup with batteries. I need a min of 2 hours with a 1500w load. Thanks guys.

    UPS | Extending the backup run-time of a UPS with an external deep-cycle battery.

    Thanks :D Would the 8 big batteries then make it go "KABOOOOM!" as discussed in the previous thread, or can I get away with it by closely monitoring the temperature?

    Thank you all for your valuable expertise and contribution - I have started a new thread on the UPS topic to avoid further derailing the OP thread on inverters here: https://mybroadband.co.za/forum/threads/ups-extending-the-backup-run-time-of-a-ups-with-an-external-deep-cycle-battery.1007092/

    UPS | Extending the backup run-time of a UPS with an external deep-cycle battery.

    That's exactly what I am looking for - I am thinking along the lines of only connecting the charged up external bank once Eskom is off and UPS running. When Eskom is restored, I will disconnect the bank and charge it myself with a standalone charger so that the UPS does not have to charge it...

    Hi Forumites Decided to start a new thread instead of derailing a recent thread started on inverters - Apologies @Dairyfarmer. https://mybroadband.co.za/forum/threads/inverter-and-batteries.997062/ I will ask the mods to move my posts here and continue the discussion. Thank you everyone for...

    Inverter and batteries

    Thanks Chuckmyster - I think I will take some internal pics of the wiring etc. and revert to you experts before I blow up my UPS :eek: Thanks for your time.

    Inverter and batteries

    Thank you kindly for your expertise Geoff. I guess it now comes down to getting a bunch of 7ah batteries or going the inverter way as with @Dairyfarmer solution.

    Inverter and batteries

    Thanks Geoff. So if I had to build a battery bank on the side, charge it separately (standalone charger) and "flip a switch" to connect the bank to the UPS once UPS is running with the load, it should be ok? Once Eskom is back on, I disconnect the bank and charge again?

    Inverter and batteries

    Will you be using this between the "critical load" and inverter? Would the inverter then charge the UPS too?

    Inverter and batteries

    @Dairyfarmer - Apologies for hijacking/derailing this thread, but all you experts are right here.. I am also exploring the same solution, however, I am contemplating possibly using my UPS so that it is "clean" power. I have a 3kva UPS (pure sine wave) - Would it be "ok" to add additional...
