    • My Sunsynk 8kw silence hack
      Hi Everyone,

      Thought I'd share this because I have noticed a few people concerned or frustrated with the fan noise from the 8kw Sunsynk inverter. I couldn't install my inverter in the garage because I do a lot of woodwork in there and I know the dust would cause issues in the fans and heatsinks. So its mounted at the end of our passage where it meets with the garage through the door. The noise at night was really an issue for me. During load shedding the fans would usually kick in. Specially when the aircons where running. This is obviously when the inverter was doing a lot of work and required cooling. Then also after load shedding when the batteries were charging the fans would come on intermittently. Bloody irritating when trying to sleep.

      The following pics is what I came up with. 5 decent quality 92mm PC fans on the vent side to constantly pull air through. Now these fans don't have the CFM or static pressure rating of the built in fans. But they are dead quite and they keep a constant steady flow of air over the heatsinks. On average, they keep the inverter 10-15 degrees cooler according to solar assistant. I have only had them in for 5 days now and the temperature has never gone over 55 degrees which is the trigger point for the built in fans. I ran all 4 aircons plus the air fryer for 30 mins and the inverter got up to 49 degrees. But when idle, it sits at 35-40 degrees. I am still waiting for a full sun day with load shedding where the MPPT's and the inverter are under a decent constant load to see what happens. Today the MPPT's where hitting around 8kw peaks while charging, and about 4kw on the inverter and it never went over 41 degrees.

      I have mounted the fans about 10mm of the exit vent so none of the holes get blocked. The idea is that when the internal fans kick in, that air can just blow through my external fans. For now, I have just hot glued the fans to the wall and hot glued a piece of trunking cover to side(proper life hack style =D). I am busy designing a decent 3D printed bracket to hold all 5 fans and clips onto the vent hole at 4 points. No alterations have been done to the inverter at all so no future warranty issues. The fans run off an external 12v supply. I have wired it through a sonoff switch with the idea to control them through home assistant based on inverter load and temps.

    • Validate my plan (or tear it apart)
      I'm ready to press go on my install (very excited). Would love some thoughts on the chosen setup, and if you have any recommendations for installers in Cape Town Northern suburbs, please DM me.

      Here's what I'm looking to set up:
      2 x Solis 6kW Inverters (S6-EH1P6K-L-PRO)
      32 x Jinko Tiger 560W (JKM560M-72HL4)
      Axe Struct Mounting system (Railed Roof Top)
      SolarMD SS 4143 14,3kWh

      Mock up of the roof attached. Mostly East / West, I've added summer / winter sunrise, midday, sunset lines to show morning and afternoon sun. I can't mount on the north facing roof (geometry won't allow).

      My thinking is to have 4 strings of 8 panels per string, with the strings of each MPPT split East and West. So MPPT1 String 1 East and MPPT 1 String 2 West.

      Was looking at 5kW Sunsynk inverters initially because the software is apparently pretty good, but the panels I'm looking at are 13.6A (over the Sunsynk rating of 13A), and the Solis 6kW at the same price looks like it makes sense with the additional headroom. Unless I'm missing something.

      The equipment above comes to R185K excluding shipping. I'd still need fuses, wire, connectors, DB board, breakers, conduit etc etc... and of course the installation.

      Does this look about right for a setup?

    • Whats the best small scale load shedding solution that can be wired to a DB
      I have a holiday cottage where I'd like to add some load shedding backup power. I want to wire it directly to some circuits on the DB, and only need it to power some lights, a router and a TV for about 4 hours (maybe boil a kettle if possible).

      It would be a huge bonus if the system was quiet as the DB is in one of the small bedrooms. Having fans whirring away while guests are trying to sleep isn't going to be cool 🤣

      What's the most affordable, long term solution here? Any specific products come to mind?
