SOMEONE STOLE THE SOALR INVERTER !

Great first job, you will only improve as time goes on. Thanks for sharing.

Sunsynk owner here, One Battery can only charge/discharge at 2.5kw (50A @ 51,2v) so to get the full 3.6kw from the the inverter when its dark.... the customer needs 2 batteries. Also the 3.6kw inverter can handle up to 7kw of solar but only when theres enough space for DC charging. i.e 3.6kw of AC inverting and the rest would be DC charging. if the batteries are 100% then solar will be clipped to 3.68kw (Max AC inverting) 7:48 - Is that generation meter bi-directional? Generation meters are essentially E-waste these days, MCS really need to abolish these. A contentious topic i know, 16:20 - 20w Grid trickle. Only needed for old PAYG meters to prevent them spinning backwards even with zero export.. With a smart meters (thats a smets1) you can safley change Grid Trickle to 0w

Hi, when I spoke with them they assured me that it will charge and discharge at the rated 3.6k, how old is your inverter ,

[@davespages]

@@brightsparkmid It's down to the battery/bms not the inverter. The 3.6kw inverter can charge up to 4.6kw DC (85A) The datasheet for the g5.3 sunsynk battery (the one in your video) says 50A charge/discharge recomended. 100A Nominal (temperature dependant) and 150A peak for 2mins over 25c. The data sheet doesn't say what temp or SOC is the optimum condition for 100A Charge/Discharge but I'm assuming >25c and then derates over 40c. Not an issue in the house, but batteries below 13c derate to 20A charge/discharge (1kw per battery) Another reason to avoid batteries in lofts. One to watch out for when installing batteries in garages or outside (that g5.3 battery is ip65 rated I believe) I have older sunsynk batteries so 50A max charge/discharge. But with 7 of them on my 8kw inverter, the bottle neck is the 190A max charging/discharging (10.4kw at 54v) of the inverter itself.

Thanks for all your details information

Is that isolator type approved to be fitted in Fusebox boards? Don't want the next eicr to flag up mixed brands of switchgear.

[@brightsparkmid]

It’s not busbar mounted so no different to a ring doorbell transformer

Hiya, just watched your video and your call for comments on the end. ;-) Having inverters and battery in my basement (a room with a size of about 20 sqm) it gets rather warm in there esp. in summer. Your installation under the staircase is an area which is too small for this hardware and there is no guarantee for proper ventilation. From what I have seen in the video, the door does not seem to have ventilation slits in it. Have a look in handbook of the inverter, section 4.2 ... "DO NOT install the inverter in the following areas: ... - Areas where the air circulation is too low." Further down in that section is a recommendation for clearance, the one with the big "WARNING" triangle. Is says: "For proper air circulation to dissipate heat, allow a clearance of approx. 50cm to the side and approx. 50cm above and below the unit. And 100cm to the front." I won't probably become a fire hazard but the inverter goes in to degraded operation mode above 45 degrees, which will happen in this space. Additionally, the power electronics in the box will age a lot quicker an cause failure. The unit is probably out of warranty as well if the manufacturer sees that the recommended clearance has not been honored. One last thing, batteries don't like heat too much, they have a comfortable temperature zone which is similar to what we humans like. Their capacity also degrades fast when they are kept fully charged and at temperatures above 35 degrees C.

Love the comment and happy to take on board, So there is a minimum 250mm clearance around the equipment and the area is going to have a fan fitted when the property is re wired as of right the now the equipment is running below 18 degrees and this is on a day where it was 30 outside,

[@davespages]

@@brightsparkmid the 3.6kw heatsink is cooled by natural convection but there is an internal fan for when the inverter gets very warm. Great point by the poster above regarding ventilation.

[@DanielStreetDynamiX]

We have our mcs coming up and after speaking to them they said you can't install under stairs as its a fire exit route would be a fail we've had to do a big run to garage tell me your thoughts

[@brightsparkmid]

So because the property is under renovation the underside of the stairs and the area around the stairs is all going to be fire boarded. I did explain all of this to my MCS assessor and I didn’t seem to be much problem with it.

[@DanielStreetDynamiX]

@@brightsparkmid love ac isolater idea totally robbing that

[@brightsparkmid]

@DanielStreetDynamiX ye I did lol, they are decent !

[@chrisp7839]

Battery and Inverter under the stairs. Is this ok these days ? A fire under the stairs will block the exit point for all upstairs rooms

[@brightsparkmid]

House is under renovation and the underside of the stairs is being double fire boarded, there was no other available location unfortunately

[@andrewpowellnz]

Nice but don't show Nick how to do those everything will be run in flexicon all the way LOL.

[@brightsparkmid]

He is the Flexicon king after all LOL
