Hi this is Mark from M Solar Power with another quick solar update in this video I'm just going
to check you through understanding your solar x-box during loadshedding or emergency power
mode in solar X terminology at the moment our house is drawing 200 to 400 watts and
our battery is at a hundred percent state of charge if your battery is at 20 percent state
of charge it's going to shut your system down and I have another video which I'll link to
below which is going to show you how to adjust the all battery capacity to change your stands
for load shedding so at the moment if the grid goes down which is going to nicely do
for us now the system is basically switched off and you could see the lights go from the garage
and you have those magnetic contactors kick in and basically our system has changed over to
EPS mode and the lights in the garage have come back on what happens though in this mode we have
a four point six kilowatt load limit so if we add load to the system and overload the inverter it's
going to shut down to self protect itself so if you just give me a moment I'm going to switch on
some loads to overload the system so we're just going to add some load to the system by turning
on the kettle and immediately you can see the load in the house go up to 2400 watts and the
solar has increased production to actually try and meet this load and draw as little power out
of the battery as possible so if we add some more load you'll see the load in the house will go up
and we're just going to add another heavy load appliance and just give it a second to kick on
and we're still at 2,500 watts and now we're going to turn on the oven to try and overload the system
there it goes to four thousand three hundred watts
with the oven on and we need one more appliance what have you got
okay there we are at 5,000 watts so we're currently overloading the system and we
were waiting for the inverter to shutdown not overloading you need to turn something
else on a heater or something and there we go we've overloaded the system so what we need to
do now is to go and switch off the items that have overloaded the system so we've gone round
and switched off the heavy load appliances and basically you can see here then vertices it's in
Fault mode so if you come to the screen and you can see the inverter says overload fault if we
touch this little red asterisks you can see it will reset the inverter and the loads are still
there and we overload it again so we've shut down even more of the heavy items and we're going to
hit the restart again and the system basically restarted and has switched the house back to
EPS mode so you can see we currently were running at a thousand four hundred watts and back to four
hundred watts so during load shedding the most important thing is to only use one heavy load item
at a time if your system goes down on changeover it's because all of the loads in your home come
on at the same time as the inverter switches over to EPS mode so it's best to go to your DB board
switch everything off and then power your lights switch back on then come and reset the inverter
and then bring the loads back slowly one at a time to make sure that you don't overload your
system so thanks for tuning in and I wish you many happy years of being empowered by the Sun!
