Installing a Sunsynk inverter

[Isetech]

Taking the cooling into consideration, today I start looking at how I plan to move the DC isolator and on/off switch out from under the unit, without making any structual modification to keep the warranty. I want the new elctrical cabinet designed specifically for the this inverter to bolt directly to the bottom. I will get it built at a local panel builder who is certified to build electrical panels.

If I fit a DC isolator into the elctrical cabinet mounted below the inverter, there will be no need to have one under the unit.

Someone said to me that customer dont want to spend money on the electrical par tof the install, the way I see it, if you have have taken the step to piss R 150 k against the wall what another R20k to make it look good and be functional., with emnough space to add more circuits and even the equipment for the EV charger, smart devices and all the otehr stuff people are adding to their properties. The old days of those silly 1 tier DB are like fax machines.

I see the 8.8 kva doesnt have the same mounting plate as the 5 kva, making the installation a little more challenging if you dont use the bolts provided and dont get the holes 100 % in line. I will make an ally template with the holes so I can just put the level on top and drill through the holes, then use either the HUS3-A6 or P6.

The fact that we dont need to worry about cooling up through the heat but rather side to side, means we can mount our panel directly to the bottom of the unit and not worry about restricting the air flow.

I would have thought there would be vents at the top on the unit, heat rises, but maybe that was taken into to consideration while designing the covers.

You don't want vents at the top as this would be an easy route for dust and small objects to fall into the unit.

Have you looked at the dust cover on the side of your inverter I keep telling people, please clean your dust cover on the fan, top or side they still collect dust.

I have installed many inverters and old type batteries (FLA/gel and AGM) and genrators, but yet to install a lithium battery and solar panels, so this will be the part I will need to pay attention.

The next step will be the panel requirements-

1/ The roof tiles, type of brackets and rails to secure the panels.

2/ Make and type of panels.

3/ The angle of the roof.

4/ Which way the roof is facing and how many panels can fit on which section of the roof.

5/ Which panels which make up each string.

6/ The max VOC and current capacity for the MPPT's.

7/ Satelite images of the roof to verify the location and space on the roof, and the location of large trees, power lines, etc, which could create shading.

8/ The size and type of cabling rqeuired from the panels to the combiner box.

9/ The route and wireways, trunking or conduit, plastic or metal.

10/ A very important step, isolation, where and what type of isolation will be used to "switch off in case of emergency".

Just a question .. don't shoot me.

Is it a good idea to put the inverter inside a cabinet ? As far as cooling is concerned, would it not be better for it to be out in the open ?

All the installs that I have seen so far are in the open

Cooling is a priority, I have learnt that when it comes to inverters and batteries, best you fit the temp probe and make sure their adequate cooling.

The plan is not to fit the inverter inside a cabinet(not initially) but build a cabinet behind the inverter and the battery to hide all the wiring. I built a CCTV cabinet like this were the equipment is surface mounted but all the plugs and cabling is hidden behind it, its not as deep as a those big network cabinets but deep enough to hide everything.
