Yes - main mcb trips. Batteries charge circa 2.5kw per hour - shower around 8kw and Zappi at 7kw.
What rate are your batteries charging at? When you say the power trips, do you mean the main 63amp mcb?
Hi. I have a Zaapi and an electric shower. When I have the car charging and turn on shower and Solar battery is charging in morning from grid (in winter months) the power trips. Is there a setting on the Zappi to stop this as I thought Zappi could counteract this issue.
Thanks all.
changed the setting last night and it did the trick - power on the zappi didnt dip when the dishwasher was spiking and battery storage charging.
thanks so it would be safe to up the limit on the zappi to 60 amps? the supply fuse is 100 amps and breaker is 63 amps on consumer board
Depends on what you set supply limit at on the Zappi, think 63amp is the norm so Zappi will automatically reduce it's power when e.g. electric shower goes on. Whilst a battery will be a constant 3.5kW, the dishwasher and washing machines will peak around 2.2-2.3 but only for short periods so will not impact draw from the Zappi
im more interested in it from the point of view of it load balancing the house - i see the zappi dial down sometimes if i have the house battery charging - 3.5kw, dishwasher on 2.5? and washing machine 2.5? zappi 7.2?
I think that the max that a Zappi can pull through at 7kW is 32amps for a single phase supply...
hi folks - i noticed on grid network settings my zappi is set to 50amps - should this be 60?
Post a pic of the schedule from your app
And go to the charger, and go into the Advanced Menu > Supply Grid and look at the DEVICE LIMIT value. 32A = 7kW
Got in touch with an installer. he says only smart chargers get the grant now.. Im looking at 2nd hand zappi v1. If I add the hub reckon Id be ok? anyone done this recently. Zappi v1 is on triple e list.. that might be enough?
Cheers.
You need to ensure they are on the same channel: https://support.myenergi.com/hc/en-gb/articles/4933265182865-Checking-the-radio-communications-channel
If you have the app open it up and tap on the Zappi symbol
If you look up yesterday (or the day you used the boost) you should see the graph going to 7kW
You can see here that mine peaked at 4kW today charging from solar
I'm wondering if the charger was running slow or finished too quickly
It’s set up for Echo +. Installer said it is set up to charge for 8 hrs from 11pm.
car is set to charge to 80%
How can I check the settings you mentioned, and what should they be? I’ve looked through the manual and at a loss!
thanks
So how long did you boost for, and what power was the Zappi boosting at?
If it's only configured for 1 hour or charging at 1.4kW then it'll only add a small amount of charge
What's the grid limit configured to on the Zappi?
Thanks for the responses. Had installer back out but issues still remain.
set up for eco++ and boost overnight but it’s only increasing charge by 10% overnight. Not much good if I need to go on a long journey!
Might give the company a call altogether.
thanks again
TAR, Good to see your still above ground😀
re
Did they also advise to park petrol cars away from the house due to the much greater fire risk?
The issue is the difficulty they have with battery fires, where containment rather than extinguishment is the current approach so if the EV is arse to wall/window tough to contain.
They are still learning, he made no bones about that.
He very clearly made the case that not all installs are meeting these regs
If I read the manual for a particular E-bike brand, it states very clearly the battery should only be charged during the day, in a room with working smoke alarms and not in a bedroom. It should also not be plugged in for more than 12 hours and not stored on the bike
Agreed, good advice : I have one and the battery does not come out
People need to learn to read the manual before using these products
Good advice for a first date also :)
I agree to some extent with the e scooters, there's been a flood of low quality chargers and batteries recently which could lead to fires.
I don't believe it's the batteries themselves at fault, more the general risk of an electrical fire
On my installation there's additional labelling on the meter box to alert firefighters to the solar panels and battery
Solar panels are required to be isolated in the event of a grid failure by using a fireman switch
The backup power supply either needs to be small (often a single socket which is labelled as always live) or requires a labelled switch within 2 metres of the front door or meter box
It appears to be the latter based on what was said.
The batteries are an issue at night, plus panels during the day.
There have also been fires in the panels due to faulty wirings.
developing their skills to deal with fires from the proliferation of batteries is ongoing
Does ESBN's responsibly not end at the cut out fuse and meter? Do they act as electricians of last resort for other state agencies?
A little off topic.
Was at a community event last event where the local fire officer was giving advice on all fire related issues.
Advice on EVs was to have them as far away from the house as possible when plugged in.
The scary, scary piece was the number of battery fires from cheap elec scooters stored in hallways/under the stairs, blocking the escape routes, especially in house with older windows that don't meet current regs for escape routes.
They don't all lead to a full fire but its an increasing problem.
Then on PV panels, they now bring the ESB in if they have a fire in a house with PV and especially battery storage, as cutting the power at the pole or meter box no longer ensures that the house is not energised.
Sleep well!
Essentially it provides an Earth reference to the DSO's PEN conductor to help mitigate against dangerous voltages arising on this.
Ah I understand, because all Installations must have an earth rod, if the grid earth fails there is still a local one. There is redundant protection.
PEN fault disconnection isn't permitted within the State due to switching of protective conductor.
It's a BS 7671 only derogation from IEC rules.
Unfortunately not all installations have an Earth electrode, though all must.
I dare say every installation does have one. Being able to find it is another story!
Mine (1980'S house) was just buried under the tarmac on the driveway. No fancy green box.. only found it because we were digging it up for another reason.
Don't worry, it's replaced properly now and accessable etc.
The whole earth rod thing is that the UK generally don't have earth rods, and putting an earth rod on an evse and putting it on a TT system was an option instead of pen fault detection etc. Open to correction here but I don't think Ireland has that requirement.
Nonsense - an Earth electrode is required at every installation within the State.
Most homes in Ireland use the Tncs system of earthing, they must have an earth rod, it has nothing at all to do with the charge point. It's merely a box (one of many) that an electrician must tick prior to carrying out restricted electrical works.
In the Uk under certain conditions, some chargepoints (those without PEN fault protection) required an earth rod to be installed.
They asked for a picture of it (green box in footpath). It must be a part of preparing the quote, although I think the Zappi is one of the few chargers that doesn't need an earth. It could be that they use a common platform for gathering quotes with multiple charger types
Why earth rod, this is a UK requirement only, not required here AFAIK
