so it's always great when we're at a trade show and we meet one of the viewers from the channel
particularly someone who is active in the comments a lot it's my pleasure to introduce Sean Scanlon
thank you very much it was our now our team renewables installer now at this show a few
days ago we discovered this sun sync inverter which i've probably described as the swiss army
knife of solar inverters but what would we know we're just getting into solar so we decided we
needed to bring in some reinforcements to find out if it is really a great product and so now what
we're about to do now is we're going to meet Keith who's the CEO of Sunsynk now Keith is passionate
about solar inverters he's had 17 years in the industry let's go and find out what he's got to
say are you ready Sean i am let's go we produce what i consider the best inverter in the world
i'm going to tell you why this is hybrid inverted but most hybrid inverters are a charger inverter
so they're ac coupled and they have a separate battery charger our inverter is what's called
bi-directional so the whole inverter reverses it becomes a charger and discharge so it does it
does both there's a single inverter the benefit is the current the power if you've got a 3.6 kilowatt
inverter it can charge the battery 3.6 kilowatt it can discharge at 3.6 kilowatt there's no
separate charger circuit so it's super efficient so this beast um seven kilowatts mppt two mppts
the benefit of the seven kilowatt mppt is it means you could put 7000 watts of solar panel up but
you've only got 3.6 kilowatt inverter so you don't need any special approvals and stop installing it
because it's got the built-in optimizers we don't need as such it doesn't use optimize it uses a
maximum peak power tracker so everybody uses the most music so we don't need to use optimizers
you use a string so it's a string that which is an americanism for series it goes into
it it's got two mppt's so this will take seven kilowatt the back the inverter side is only 3.6
you're never going to use more than 3.6 it's ac coupled so if you have a peak demand it will
just pull from the ac because 3.6 if you put 10 kilowatts of batteries and you're gonna charge it
off a seven kilowatt array it would probably just about charge in the uk one point three one two
sun hours some radiance so it'll just about charge ten kilowatts it will then discharge um over three
hours at full power and you you want to know all night that's a lot of energy so at 3.6 is perfect
for the uk it's absolutely perfect um you look at this you click on the button here you see the flow
so you see the two mppts you can prioritize if you want the to charge the battery first or you
want to use it my recommendation really would you use the power if you don't understand the system
if you've got an accommodate seven or an octopus agile tariff or one of those type of tariffs
you could charge the batteries at night then then it's a different scenario if you haven't got that
title you're just going to rely on your solar then use your solar first and what you don't
use in the solar dump into the battery but this be this this beauty can give you enough power
to charge your battery and use what you can at the same time okay it's very very special
on the front you've got these sort of i love these the dials i saw something about hot water as well
what is it what's that if you fill the batteries up and the batteries are completely full then you
can switch it on an auxiliary load and you can then transfer it to the hot water tank no extra
parts it's built in you don't need to buy any extra everything is a single piece unit so this is
this is the smallest because we go from a 3.6 yeah and we go right up to so 16 kilo and very soon 50
kilowatts and these things have been installed in hospitals and schools as well as houses but
this one we've designed especially for the uk it's a UK model that's why it's got seven kilowatt mppt
it's got a beast of an mppt but the other side the inverters it was a bit but it doesn't need it
because you're never ever going to use anything bigger than that it's impossible you put 10
kilowatt what house has got can take bigger than seven kilowatt you know not many no so averaging
what would you fit normally we use optimizers it'll be six kilowatts into a three point six
yeah would you inverter so if you have a flat roof without without shadowing
yeah then you wouldn't need to use an optimizer there's no there's no benefit you've got losses
because you're gonna run export power because that you know the cost of electricity now is crazy so
always say it's customers yeah if you can keep everything that you've got yeah because i say
to people you know because the guy said you know you said well we get ap a kilowatt hour for expo
that's brilliant yeah put your buyer back at 30p yeah because the first thing you do is you you're
basically running your house and you're empty you're at work and then you come home at night
and the first thing you do is turn the light on and then you're buying it back again so you
dump it in the battery and the other thing is i always say people make sure you've got batteries
are going to last you yeah because don't buy cheap so we're using either k-tail or byd cells
the 6 000 cycle because what you don't want to do is if you get something that's cheap cheap cheap
and you just waste your money yeah you know you just get something that's going to last you you're
going to fit it and forget it and it's going to give you years of service by cheap pay to us
okay so you can program from the invert itself from the screen itself or you can program it
from the app and our app has um for example force notification so if you've got a power cut
you've got a problem it will send you even the installer a text message so you know if you've
got like 100 systems you'll get a text message and say look you've got a problem at 24 redwood
way or whatever and you've got a problem there and you have the message and you'll see straight
away from your phone you say oh well i need just to just make an adjustment on the settings or
and you can do it from your phone and the customer might even know there's been an issue so we'll
just do a backup as well if you have the power out exactly so you would put two you would switch
put two consume units on normally on a smaller inverter you put two consumers you have your
essential loads and your non-essential loads non-essential loads ac coupled it's a single
wire here into your consumer unit if you want non-essential you would take a separate wire here
to a separate consumer unit i would always suggest put a change of a switch because if you ever want
to remove it or maintenance or anything like that you've got you've got a change over switch then it
would give you allow your essentials still to work but then you've got your essentials which is your
lights maybe a couple of sockets your freezers and if you have a power outage and i'm watching on the
news all these power outages i'm getting people that are talking to us said you know getting
power outside the other thing is it can load shape what's the um change over time oh very expensive
yeah and and all certificates bi-directional so if you're using it if you fit it on an existing
system so you have an existing system you've got an inverter and everything else and you've got an
export you you don't want to touch the existence you can't do you put a ct coil on the grid
coming in you put this to the consumer unit as you start to export this charges the battery
if you import from the grid this will discharge the battery automatically and the inverters go
both ways and that's the benefit of a bi-directional because then it's full power both
ways if you want to and especially you could fit it onto a large installation and you need a small
battery and what comes into that battery is free power i'm impressed i'm convincing you and what
sizes are the batteries coming so the batteries come in 5.2 kilowatt units this is 5.2 kilowatt
these ones are a k-tail cell so we do a k-tail cell and then we also do a byd equivalent six
thousand cycles um and you can power you can put up to 16 of these in one bank they just link up
yeah and they'll so the batteries will have a mass so you have a master battery and the
batteries you all set up your batteries as one master and then the batteries will communicate
to each other and then the battery then the master battery will communicate to the master inverter
if you've got multiple inverters and that's used by a can bus cable and so you'll see on the screen
the exact status of the batteries so everything's talking to each other okay can the battery stack
yeah you could do it on the you could do wall mount or you could do it stack mounted
you could just you could this cover removes and it will go the other way so it'll go either way and
that's actually a rack mounted inverter totally integrated with agile totally integrated with some
of the other tariffs on the apps yeah but you know we tried to sort of as we tried to cover
everything before everything yeah yeah one of the things one of the things also is in caravan parks
yeah so where you've got a limited power supply 16 amp switch in a caravan yep and now with the
change of all these ev everyone's gonna have ev yeah so uh electric vehicles you're gonna have
to work car charger next to a caravan and you've got 16 amps how are you going to put a car charger
next to it on a 60 amp feed you know impossible but you can use this on what we call load shaving
it can trickle charge the battery maybe at five amp about a kilowatt it will trickle charge at one
kilowatt and then you can boost it out and give you 40 amp out so it can charge you your vehicle
it's it's good and that that's a major feature having this load shaving feature
so you've got pe peak power shaving and you can limit it as low as one kilowatt
so okay so hopefully we'll convince you to try one yeah yeah i do want to try one thank you thank
you much thank you yeah i've got a job coming up yeah i might uh put that instead thank you
so sean you've had the full barrage of Keith sales patter there i have this
Sunsynk inverter what what's your thoughts about the product very very impressive
everything in one box like i said uh it's never obviously got battery storage yeah uh you've got
your battery protector as well so if you do lose energy you've got that as well and also does your
hot water so you think you're going to give one a try definitely well stay tuned to see what Sean
does with the sun sink inverters hopefully we'll be seeing it on the channel soon so Sean thanks
very much we'll uh we'll be into with some more stuff in the future thanks for having me
your solar array is obviously got some soda that's freshly cut this one you get smart thanks
