  1. 4 x Deltec BR12V100 Batteries for sale Bought if February 2019 No need for it any longer as I have upgrade to LiFePO4
  2. Genuine RCT Axpert 5k (5000VA/5000W) for sale R9000.00 Was bought in February 2019 (original invoice available) and only connected to flooded batteries. Original software (V74.30) Parallel connection port and cables Due to the fact that I want to configure my new PV panels in a serial fashion, it is no longer suited to my needs. Available ex Swartland
  3. Hi Chris

     

    in 2018 you mentioned "My partner in crime (Chris-R) is about to import good quality solar accessories (SPDs, DC disconnects, DC (and AC) breakers,  fuses, MC4 connectors cabling etc). Watch this space"

     

    Do you know if he has DC breakers (16A) or other can you recommend a few reputable brands

     

    tks

     

  4. Hi Coulomb as always you are a great source of information - tks Question - if I want to use this inverter with LifePO4 batteries, is there an update that would allow it to see these, or, what would you suggest I use to charge the batteries with (I will have 2 x 48v 120ah 6.1kwh LiFePO4 Wall Mount Solar UPS Battery (2nd Life) batteries each with a BMS. I am considering using your string configuration (as per another mail) or if I can't cost-effectively charge the batteries add another small inverter to take care of the battery charging. Stand alone MPPT controllers seems ridiculously expensive (give that I will have 1 string of 4 x Canadian solar 410 PLUS 1 string of 8 x Canadian Solar 410) panels
  5. I have an Axpert 5K 5000VA/5000W (not clone) and want to know why I should upgrade the firmware from 74.3 that it came with to a later version
  6. It has taken quite some time, but finally the minister of finance has approved the budget for an upgrade/enhancement Current Equipment RCT-Axpert 5K 4 x AGM Batteries 100Ah Dedicated DB for Inverter IN/OUT puts with circuit breakers Prepaid Electricity meter feeding main board All circuits (excluding geyser) can be fed by the Axpert in case of load shedding / power failure - we manage 4 hours on LED lights, DSTV and 2 x LED TV's UPGRADE 1. Install 12 x Canadian 410W Solar Super High Power Poly PERC HiKU Solar Panel with MC4 4 x facing North East - max roofspace for panels. These would be 12-14m from the inverter and batteries 8 x facing North West - can install up to 16 panels. These would be 10-12m from the inverter and batteries 2. Install 2 x Dyness B3 3.6kWh Lithium-Ion Batteries 3. Install additional MPPT - see questions for more details 4. Future (not today slave Inverter (Axpert / Kodak ?) Some questions: 1. I am in two minds how to run the strings (2 x serial panels and 2 x parallel panels per string?) This would mean at least 3 strings which means a change of MPPT. 2. What would be a value for money MPPT given that I might end up with 5 strings or an MPPT that can handle bigger strings 3. I have seen that there is a move to micro MPPT's (1/string) - what are the pro's and cons? 4. Does the orientation of the panel matter (i.e. the N/E string will be orientated portrait and the N/W landscape due to available roof space) Any other recommendations would be appreciated Tks
  7. Hi Erastus Has this happened, is it happening etc?
  8. PLEASE ADVISE ON CONFIGURATION It took some scratching but I got my Energy Consumption Meter out of the cupboard and here are the results from the main Eskom feed at our current premises in PE. We will be relocating to Darling WC and I want to ultimately disconnect from the grid (with existing prepaid as an emergency backup). Note: Swartland Municipality apparently do not have the same requirements as Cape Town for PV. As stated previously, my ultimate aim is to disconnect from ESKOM, and to this aim I started with a 5kW Axpert (5000W) to deal with load shedding, and will most probably have to add another parallel unit. Since we are relocating to a far smaller stand in WC, the lawnmower (2000W) will be replaced with a much smaller unit. We will still have a 1.2kW pool pump, and unless someone has a cost-effective solar/PV friendly unit, this will be it (we are putting in a new pool with roof heating hence the bigger motor). North facing roof space is limited, so I am looking for the most efficient panels (400W +). Next issue is that the inverters, batteries and switch gear will be stored in the basement and then linked back to the main DB. The feed from the existing prepaid meter will be rerouted to a new DB with a breaker and Change Over switch for emergency power. BTW, I also have a MaxWatt 5500W petrol gennie that I could use for my MIG welder and other power tools [if need be] Major consumers currently: a. Pool pump b. Heat pump & separate geyser c. Borehole pump and pressure pump (irrigation) d. Lawn mower / weed eater once a week (mostly at startup) 1. Daily consumption profile This profile does not change much, always peaks at 9am when pool pump kicks in 2. April 2019 I only started measuring on the morning of 10 April, so the real picture emerges from 11 April 2019. Note the peak consumption of 13.68kW on 20 April. This was mostly due to me using a chop saw for cutting aluminium tubing. 3. May 2019 Peak consumption of 8.44kw on 7 May at 9:39 can be attributed to washing machine + weed eater/lawn mower + pool pump + Heat pump
  9. So today I installed a new 5KVa Axpert. It connects to the plugs and lights (on EL) via a SF2P-63A which separates Grid power from Inverter power Now for a strange one: Everything was working fine before load shedding with the ACDC 2 pole change over working like a charm. Load shedding came and 3.5hrs later we were back to Grid power. Switched change over back to Grid and all fine. Switched power on to charge Inverter and all fine. 10 Minutes later EL tripped - no problem switched all circuits off. Will not reset. Change over to all off (middle position) EL resets. Switch to Grid power and EL trips immediately even with all breakers down. Now switch to inverter, and EL resets. Even with inverter being charged (circuit from main switch with own EL - sub DB), EL still good. Even if I unplug the mains to inverter for charge (at this stage it still goes through a plug - will go through breaker tomorrow) with change over set to Grid, still full trip. Interim solution - Back to running lights and plugs on EL from inverter. Inverter connected to grid via a secondary circuit (sub DB with own EL) and no trips. So what is common: Earth from Axpert inverter output is connected to Earth at Main DB. I have a few LED circuits which seems to have a leakage (flashing LED's). So tomorrow the search starts, only question is where and how? I have includes a schematic of the installation for ease of reference Any advise would be appreciated, and if this post is in the wrong section, please move tks Cardiff Inverter.pdf

  11. Neutral from mains is isolated through change over switch, so neutrals do not meet
  12. Hi everyone After many years we have finally started down this road. After 7 hours of loadshedding (5 minute break in between) it was time to install the following: Axpert 5K inverter (48v, 5000w) 4 x Delco AGM BR12V-100 Batteries (connected in series) 1 x AC-DC SF2P-063 Change over switch Reasoning behind config: 1. Axpert 5K will in the next year be connected in parallel with another Axpert 5K 2. Axpert supports 80A Solar charge current through MPPT 3. We will install solar panels in our new house (relocating to the Swartland later this year) 4. We will increase / reconfig the batteries over a period of time 5. Current need is to drive 2 x laptops, 1 x ADSL router, 2 x LED TV's with DSTV, Drive a number of LED lights, Drive 2 x A+ Fridges and 1 x A+ freezer I am experimenting to see if I can get 4hrs run time from the 100AH AGM battery and to see what the discharge level is. Also note that I have left the Axpert in default config. 1 Issue: Since adding the change over switch, the LED's in my kitchen (4 x 3W) are flashing when switched off. This was even before I connected the output from the inverter. Seems that I might have to replace those globes - strange but true. 1 Question: What should I do with the inverter earth.? Can I connect it to the house earth in my DB? ANY COMMENTS AND SUGGESTIONS WILL BE APPRECIATED Cardiff Inverter.pdf
