  1. Our estate uses 24V Mecer lookalikes, with 2 * 12V 105AH Enertec deep cycle batteries. A very common event is that 1 battery gets tired after 2-3 years, and either will not hold a charge, or will not charge beyond 12.5V I know it is not good practice to replace 1 battery only, as the batteries are now unbalanced, but most of the above failures are due to unbalancing anyway. What is the worst that can happen if one replaces 1 battery only, and monitor the balancing going forward with a voltmeter? If the older battery fails, it was due to be replaced anyway. If the new
  2. This looks interesting:) Defy is launching a hybrid solar mains fridge and freezer this month (Feb 2021) 3 * 30W panels come with the appliance and use solar power to keep the fridge or freezer powered when the sun is out, falling back to mains as required. https://stuff.co.za/2021/02/11/solar-hybrid-fridge-freezer-south-africa/ https://www.businessinsider.co.za/defy-launches-solar-powered-fridges-freezers-in-sa-costs-under-r6000-with-panel-2021-2 https://www.defy.co.za/solar-hybrid
  3. Thanks for the suggestions! I presume Sonoff would need an App or Wifi connection? After some research I am looking at one of the following 1. Sinotimer (12V option available) TM618 Universal Input 5V 12V 24V DC/AC 7 Days Programmable Weekly Timer Module for Gate Automation and Solar Controls Usage: The TM618 timer MODULE can open or close kinds of electrical apparatus and power automatically, according to the preset time, the items can be streetlight, neon light (sign), billboard, electrical appliances, broadcast equipment etc... 2. Omron H5F (220V only, no
  4. Question for the techies out there:) I am a trustee for a body corporate, mix of commercial and residential units. Access control is the normal sliding gate. The current Centurion gate motor does the job just fine, but we would like to tweak the operation slightly The Centurion gate controller has a built in timer, and we use this to open the gate at 6am and close it at 7pm (Mon to Sun) The gate has to stay open 6am-7pm for the commercial units (medical centre), but after 2pm Sat and all of Sun, we would prefer the gate to close. The current setup does not allow for di
  5. One Deal a Day has this on offer
  6. I have been involved with body corporates for many years, and you are right, it is often difficult to change the status quo. I suspect that the aesthetics issue will be a big factor, an unsightly installation will not go down well. Also if the roof tiles are damaged in any way, this will be a big no-no. It would be better if the body corporate took the lead, but this needs a solar champion to drive it.
  7. Very interesting discussion, thank you! I have a house that is now rented out, but the roof is almost perfect for panels, being east and north facing. We are now staying in a complex of 71 free standing simplexes and duplexes, facing in all directions, depending on the unit. Some of the garages (including ours) have a nice north facing garage. Ours is a single garage (3mx5m) as are most others, only a few double garages. Could fit at least 6 panels on it. My question is: Are architects in future going to start designing residences to be 'sun friendly' ie making th
  8. This is very normal. I have noted this with Enertec batteries, and the battery data sheet confirms it, there is a sharp drop initially to approx 24.8V within the first 15 minutes, then a long flat discharge of several hours to 24.0V
  9. Hi iops, Slightly off topic, but I would like to ask you about your Synapse 3.0+ 24V inverter, as the residential complex I live in on the KZN South Coast has a few of these units installed, together with many CBSolar 24V inverters and a handful of Mecers The CBSolar inverters have been the standard for 2 years and apart from a few failures have performed well. We are still getting to know the Synapse and Mecer. One issue we have noted with the Synapse 3.0+ is that the fan runs continuously, this is not the case with the CBSolar and Mecer. Do you know if the Synapse is a Vo
  10. I understand that when [05] is set to Use, that this enables [26] [27] [29] What are the results of using Fld and Agm? Fld seems to force 26,27, and 29 to the default values? Does Agm do the same? When would one ever want to use Fld or Agm? It is very confusing to have setting 5 default to Fld, not realizing that it has an impact on other important settings!
  11. Veerry interesting, thanks McDuffy!
  12. Hi McDuffy, How do you measure your battery voltages - external voltmeter, Axpert display, or RS232 port and PC? I would really like to see a comprehensive test of the Axpert performance, but using lab equipment to accurately measure volts and amps. Not sure I trust the measurements displayed by the Axpert Regards, Solo
  13. Impressive! Did you import the Flukso unit directory from the suppliers, or are they available locally?
