Hi all, Stupid question please, I have 2 x parallel Sunsynk 5KW Hybrid Inverters with one SOLAR MD 7.4k SS4037 battery connected, but I need more battery. The problem is that the SolarMD batteries are so expensive. Is it possible to have the 1 inverter running the SolarMD battery and the other inverted running 2 x 5.5KWh Hubble batteries without having to rewire etc?

Good idea, thanks

Thanks soooooo much!

Hi @Bloubul7 Please which register are you reading to get the Grid status? Please help me out of my misery! Could you show me the function and check blocks please!

Thanks so much!

Hi all Silly question, where do I find the Software version, on the main screen I see On the main screen I just see ID: xxxx COMM: xxxx- MCU: xxxx? Are those the software version(s)? Thanks!

Just waiting for the other USB RS485, I agree, should only be the MPPT readings that I would need from the slave, I did disable the other flows, just using the ModbusRead & Inverter monitoring flows

aaah brilliant thanks so much!

Hi Rautenk, I also have 2 units in parallel, just to confirm, do you have 2 x USB to RS485, so one connection goes to Master, let say on /dev/ttyUSB0 and the other to the slave on /dev/ttyUSB1? And then running 2 node-red configs, one for each of the inverters? I have mine connected to the Master, but I have 1 x MPPT on Master and 2 x MPPT on the slave, but I only see the one on the Master. On another note, how the (*&*#^#&*^#&^ do you get from this msg.payload = { 'fc': 3, 'unitid': 1, 'address': 186, 'quantity': 1 }; msg.topic = "Solar_PV1_Power" return msg; to the correct part of the Synsynk_modbus document please?! My Mandarin is failing me big time.... Thanks for the awesome info on this

Ha ha, I'm in Glenferness, Midrand and Dylan.. I'm not allowed to post the company details as per the forum rules (you can dm me if you need Dylan's contact details). Added the 2 geysers to AUX output, so when there is no generation or Eskom, battery will be drawn to 96% and the geysers will switched off

Thank you!

Thanks Sc00bs, but where do you plug in the cable on the inverter? Do you perhaps have a picture of the plugin?

Hi All, I had 2 x 5KW Sunsynk Invertors installed recently and I'm relatively new to Solar. I download the SolarMan app, but I'm not impressed with it. I think I will go the same route as what you guys did. I know Raspberry Pi's as I use them every day in my job. Just a couple of questions, if you do not mind please. I'm confused on the connection I take it I would need 2 of them, one to the master and one to the slave? Do they connect in place of the dongle? Or where would they connect to the inverters?

Hi all, My new install, thanks Dylan, you guys did a stellar job 18 x 450W panels 2 x 5KW Sunsynk Invertors 1 x Solar MD 7.4kwh battery I can highly recommend Dylan and his team, no question was unanswered and even support during the Easter weekend was not a problem for him

That does make sense, let me start to shop around and see what I can afford...

Thanks so much

Thanks so much for all the answers, I think I'm understanding this better. Is there any thing in favour keeping a 3 phase system? My understanding is that you only need 3 phase for big pumps etc, is this still valid for modern day designs? Am I making a mistake in converting to single phase? I think I'm going to tackle the geysers 1st, convert them to solar and then rethink my consumption Thanks again for the advice

Hi all, I have 3-phase on a plot in Kyalami, I want to convert it to single phase at some stage as I do not use the 3 phase at all. I have the Engage Clip on system, one for each phase, that produces a graph like this for the year My question is and I do know it is very generic, how big of a solar solution will be enough for my needs? To get as close as possible to go off grid. As I want to convert to single phase, do I add all the phases together? But what then, how do I calculate what is needed, any advice please?
