  1. Mecer 5kVa settings and monitoring

    No problem, have your laughs... I have a 10kVA inverter with 6.2kWp and 120A charging capacity that cost me R15k, I can afford a few giggles at my expense! PS - Inverter cost only for 2 MKS5k in parralel, the rest of the stuff cost an arm+
  2. Geyserworx PV geyser unit

    I dont know this system but having glanced through the website there is no reason that I can think of for it not to work. PV panels feeding an inverter with grid backup - output to the geyser - no problem. Geyserwise do a system which I have used successfully, but Geyserwise uses a Titanium DC element whereas the Geyserworx system uses a standard AC element and so any geyser could be retro-fitted without the need for plumbing. It would basically boil down to the cost of the system and Return on Investment.

    Go to this page; http://forums.aeva.asn.au/viewtopic.php?t=4332 and read thru the firmware section.
  4. Grid tie without battery backup question

    ...and then a cloud came past... Batteries are required for stability of supply when supplying a load from an inverter, just because it can be done without batteries doesn't make it a smart idea.

  6. Mecer 5kVa settings and monitoring

    Yes, Axpert firmware has a bit of a bug in the charge algorithm that allows the system to go to float too early under certain conditions, the firmware upgrade improves this issue.
  7. Mecer 5kVa settings and monitoring

    Hi @egemnaar The software that the forum will recommend is ICC (http://iccsoftware.co.za/), which will give you good information and control over your system. I use an old Windows laptop in the solar room which I can control remotely using Remote Desktop, I am not sure how this would be done using a RasPi but I am sure others can advise you on this. If using ICC then it is HIGHLY recommended that you install the Victron BMV-702 (ask @Camel) which will greatly improve how the batteries are controlled. Get an HA-01 (ask @Chris-R) which will maintain charge balance between the batteries which is a big concern with series connected batteries. When budget allows I would suggest upgrading to 8 panels (if currently connected in 3p2s) or 9 panels (if currently connected 2p3s) which would be better suited to your current 200Ah battery bank.
  8. Newbie mistakes on first solar install

    Drawing power directly off the series connected batteries is a mistake unless you are drawing identical loads off each battery. Even similar fans doesn't guarantee similar loads as the operating conditions of the fans may vary. If you MUST do it then take the power off across the full bank (12/24/36/48v - whatever your bank voltage is) and the put 1/2/3/4 fans in series - or just cough up a few pennies for a 12v DC transformer. You could pray that your HA will cope with the imbalance, but if you get it wrong it could cost you a new HA and a new battery bank - and a new 12v DC transformer because you are unlikely to make the same mistake twice!
  9. Sabre prepaid meters

    I have a PDF for a Sabre Mk5 from Landis Gyr which is probably the same piece of kit - drop me a PM if you would like me to mail it to you.
  10. Pairing AGM and Gel batteries

    It is usually not recommended to mix batteries of different chemistries.
  11. Axpert Inveter and gel batteries.

    HUH??? I guess the short answer is YES and NO... Axpert inverters are compatible with various types of batteries, but not all types of batteries... Axpert inverters are available in a varying range, all of which require battery banks of either 24v or 48v (nominal) - the max power rating (Ah) of the connected bank would need to be carefully selected depending on the max grid charging current of the selected inverter if used as UPS type backup only, or the available PV overhead if charging via PV panels in an off-grid/grid-assist setup. What batteries have you been offered and what would you like to accomplish?
  12. DIY Powerwall with 18650 batteries

    Any hints as to where to look for the cells?
  13. DIY Powerwall with 18650 batteries

    I am guessing 182s14p 182p14s... I would love to give that a go - where did you find 2548 cells, what did it cost, are you using a BMS, are you happy with the resulting performance?
  14. Water harvesting and use, same logic as solar systems.

    Great job. Out of interest why have you finished it off below surrounding ground level, or is that an optical illusion?
  15. Ok, I was just looking at the pop-up when you hover over 6.300kW on the ladder which says 12x 300. I guess better info available elsewhere.
