  1. Hi Richard Thanks, I will most prob opt for the discharge test. My wife might finally realise I have lost it if I test my batteries for COVID. ;)
  2. Hi All Hope some one can advise. I have a 5 KVA RCT (Axpert) 48V inverter. Currently I am running 4 x 12v 90 AH batteries but I think one or 2 of them have died. When in charge it goes up to the predetermined 54v but when we shed the voltage drops to about 50v. The draw is about 500w which used to last 6- 8 hours (plus) , now its about 90 min. I would like to know if there is a way to run a stress test or similar to see the battery health? Thanks
  3. I did yes. Basically got all the needed components from various stores. Worked out the neutral bar with a combination of multi meter testing and cowboy method, well only one cowboy method. Ensured I had the correct wiring diagram about 5 times over, ensured my life insurance was set to cover stupid stuff and then set it all up. All I need to do now is put the trunking in so that it looks a tad better.
  4. Hi All, Just a big thank you for everyone's help and advice. I got the inverter up and running and we can now enjoy all the luxuries of a modern home such as lights and television during the mandatory community load shedding.
  5. Hi Bloubul7 That line is still confusing me. So I cannot bring the neutral from thee inverter into here?
  6. Awesome thanks, I see that there are inline fuse holders and then the one you mentioned in the google search. apart from price difference and fuse type, any benefits to the Mersen for example Ideally the fuses to batteries can live in a box on the wall but just curious as there is quite the price difference
  7. So, final piece of advice needed. Basically if I follow all the advice I will need the following I have a 5KVA ,48 volt inverter and 4 x 12v 95AH batteries in series I have it that the system can put out 23 Amps max (5000w/220v = 22.2) DB Board: 1 x earth leakage CB (40amp) 1x normal CB (40amps) Out side DB board: 1 x manual change over switch Inverter 1 x 100 amp DC fuse for the batteries, or do I need one on both positive and negative? And then all the wiring and trunking and stuff
  8. Thanks for the diagram. Because I am an absolute novice with this. On your other diagram the earth seems to be its own circuit connecting only to Eskom power source. what closes the loop? I really appreciate all the help. I will head off tomorrow to start getting the needed switches etc. Thanks
  9. Hi Every one Thank you for the feedback!!! so from what I understand. Outgoing: I will need to add a CB into the DB board connect that the Inverter ( take a connection from earth to 'power; that and then remove the other connections to lights and plugs) Incoming: I will need a CB which runs into an earth connection and from there powers the various other CB (Lights + Plugs) Batteries: I will need to buy a place a fuse box between batteries and inverter to protect that connection. Manual override switch ultimately is optional but would be between the outgoing
  10. Hi, I have an Axpert 5KVA inverter that I want to connect to the DB board to run the lights and plugs. It was installed at my previous place and was pretty straight forward (Output and Input of 220 volt and then DB board connections, nothing was connected in between, this is how I inherited it and worked flawlessly for 3 years.) , however I have requested several quotes from various electicians and its nearly more to install than to actually buy the system. (pricing is around the 8 - 10K for the installation and parts ) My question revolves around the connectivity of the Inverter t
  11. Thanks for the responses. Earthed the invertor and it is now working properly. Appreciate the help.
  12. Hi I need a bit of assistance. I have an Axpert inverter set up as a battery back up solution. I only run the lights and the plugs off the system and ignore the geyser and the stove. It runs off the system constantly for the fail over, so no manually switching. I have attached the wiring from the invertor alone. So have not included the 'normal' grid power circuit. The issue I have is that when on the grid and earth is triggered the invertor kicks in automatically and power is restored to the plugs and lights. Obviously I need it to stay earthed and not restore power in
  13. Thanks Coulomb. No panels just yet, will tackle that one later in the year where I would ideally like to run everything off the panels during the day and then batteries in the evening. First however have to get approval from body corporate and all that and then the final hurdle; the finance manager, aka the wife...
  14. Thanks, appreciate the feedback and advice, will dive into the programming this evening and check where I can set the charge voltage to the 56.4V. While I am at it, what should the cut off be? Again thanks.
