  1. Seems that this topic has already been covered in some depth, found the post by Bloubul7 looks like he is doing pretty much what I would like to do
  2. Was thinking of using https://esphome.io/ to manage the connection to the Inverter and switching on/off of the Sonoff's with Tasmota on them., Anyone had any experience or any other suggestions?
  3. Does anyone know if there is an easy way to do this with a Sunsynk inverter (I know it is possible, I would rather just not be reinventing the wheel)? I assume that I would be connecting the Raspberry Pi to the CanBus or RS 485 ports on the Inverter using an interface of some sorts. I know that the ICC software is not compatible as it only seesm to work with the AXPert inverters. I am looking for a way to switch on/off certain devices on my power network when certain conditions happen on the inverter, Pool on when there is excess power, Borehole off when there is load shedding etc.
  4. Looks like they have another site up https://www.thewattstorsa.co.za/ Same batteries, no payment via credit card, optional CANBUS connection, different phone number Domain created Nov 2020
  5. Hi Guys I am looking for something along the lines of the ICC APM software that can control Sonoff devices based on what's specified events on a Sunsynk Inverter. My understanding is that the ICC software is not compatible with the Sunsynk inverters Specifically I would like to disconnect some items from drawing power when the Inverter detects load shedding. It is unfortunately not possible to add them onto the non-essential loads. If there are any other suggestions as to how I could accomplish this I am open to suggestions. Thanks JohnB
  6. They have a new site up, same pictures as the old one https://www.bestsolarsolutions.co.za/ R50k for 24kw of battery
  7. Hi Leslie, Thank you for your review of your ESS System. You could perhaps look at a "soft starter" for your compressor which does not require the boost of electricity to get going. Speak to Neels at https://www.cfptechnologies.co.za/workshopspeedcontrol/ and he will be able to advise what will be suitable for your application. Otherwise from RS Electronics https://za.rs-online.com/web/p/motor-starters/2096340/ JohnB
  8. Have an Efergy Engage already which probably gives me enough info about my energy usage I liked that the Sense will isolate the power usage to a usage by device. Was wondering if anyone has any experience with it.
  9. Hi I was looking online for energy usage monitors and saw this recommend in the US on CNET, has anyone seen these locally/tried one out? I am interested to know what the usage of it is like as it looks very granular on the usage reports https://sense.com/ Thanks JohnB
  10. Thanks @Vassen, seldom pull more than 2kw at night so don't need batteries to run a 10kw load. The large PV panel array would be to offset non-essential items that I would like to cover during daylight hours with my PV panels when funds allow. Thinking of starting with a 5kw Inverter and then I can slot another one on later if I want rather than spending the extra for the 8kw out the box.
  11. Can someone tell me, I am looking at either a Sunsynk 8kw system or a 5kw and then perhaps adding a second 5kw on a bit later. If I have 2 x 5kw Sunsynk inverters in parallel, would that allow me to connect 2 x 6500w of panels using all 4 mppt controllers or are there some restrictions when using the inverters in parallel? Thanks
  12. Thank you @Achmat & @Vassen for the correction. I assume that you would have to have a sensor in place so that power is not fed back into the grid, is that correct?
  13. Will Prowse video on running in parallel
  14. So, this is my understanding, please note that I am no expert on this and would like to hear from anyone that knows more about it than I do. It is obviously not an option to have batteries of different chemistries connected in parallel due to different operating voltages. From what I understand, the state of charge of the battery packs running in parallel will always be the same as long as they are connected together and the amperage supplied will be in proportion to their capacities. The way it was explained to me was to think of it as having a number of water tanks of the same hei
