Yes/No ,this is the process, when you apply for registration , you apply for approval to install the pv panels On approval , you get an official letter, you get 3 month to install the pv panels Within the 3 months you submit the COC and line drawings , then you wait for final approval letter of commission to switch on PV

Yes but if you install an inverter on the approved list you will need engineer sign-off , non-neg. on all approved list inverters

The line drawing guide/objects/components/glossary is on the City of Cape Town website https://resource.capetown.gov.za/documentcentre/Documents/Procedures, guidelines and regulations/Embedded generation schematic drawings SK5276.pdf Depending on your layout the line drawing is done using those components

There are a few application types GRID-TIED SSEG GRID-TIED HYBRID SSEG STANDBY SSEG OFF-GRID https://www.capetown.gov.za/City-Connect/Apply/Municipal-services/Electricity/apply-for-authorisation-to-install-a-small-scale-embedded-generation-system The 2 x Grid Tied applications must have one of the City of Cape Town approved inverters The Standby and Off-Grid applications you cannot use any inverter on the City of Cape Town list (I know , why not, that is the process) If you still need some power from Grid you will be Standby Segg application If you totally off-grid and not not need any power from grid then you will be Off-grid application

Nice BrettB , my garage gets hot and was thinking to do the same but for my MPPT ,

I am in the market for a DC (DC Current, DC Voltage) clamp meter, home/hobby use Any recommendations?

Maybe post some pics of the install, I have recently upgraded the inverter and a few things changed since the old inverter install, the electrician added indicator lights, another isolator and surge protector, could be SANs updates or just industry requirements but he explained why and I understood the reasoning

You will just need the below settings for the battery when setting up ESS via VEConfigure The rest you do via the Remote Console ESS Settings ------------ 0.005C 0.25C 0.7C 2C Settings ----------- Low Shut Down Low Restart Low Pre-Alarm Absorption Float Sustain Restart Offset

I do not know any installlers in Langebaan but ... Local electrician can add meter to db board and software changes can be done online, if you connected Do you already have ESS assistant installed on the inverter ? Check under settings ,ESS Find below some online info https://www.victronenergy.com/live/ess:quick-installation-guide

Thx for the correction, meant to type 42V

As far as I understand Hubble BMS will protect the battery at 46V , which is +/- 40%

I have a variable ac pool pump, when it prime it spikes for a few seconds, then for filtering low usage, for kreepy it ramps medium usage, so very efficient Might be an alternative to the DC pump

The approval process does take long +/- 2 months, maybe COC technician is waiting for feedback from installer Try and get COC technicians details from installer on email confirmation received from COC

Doubt it will overshoot more than 40 volt, which is 10% per panel

ok, if 550v limit per string, then you can add extra 3 panels per string MPPT Operating Voltage Range (V)125~550 MPPT 1 - 46.4 V x 11 = 510.4 v MPPT 2 - 46.4 V x 11 = 510.4 v

MPPT Operating Voltage Range (V)125~550 MPPT 1 - 46.4 V x 8 = 371.2 v MPPT 2 - 46.4 V x 8 = 371.2 v MPPT 1 + MPPT 2 = 742.4 v Looks like you already oversubscribed, unless the limit of 550v is per MPPT

These graphs are just sad 😪

Hubble you ever going to bring back the cell voltages and cycles to the cloud link?

I have the Hubble Cloud link and cannot see all this info , any way to enable it in Cloud link, Cell Voltage and Cycles?

Hi Glen , the registration process takes long (months) and "easy" if you have everything, I do not know anyone but if I was in your shoes, I could check the sapvia website for an approved installer and ask them to come to do an assessment of installation and assist with registration

You have a grid-tied inverter that is on the City Of Cape Town approved grid-tied inverter list which means you automatically have to apply for grid-tied application which will require engineer sign-off as well You can do your own registration, it is free but you will need engineer sign-off, technical drawings and COC, everything is on the City of Cape Town's website

Where you located ?

AFAIK there must be load otherwise MPPT will throttle down, it will not pull max output if no load for it, at least that is how standalone MPPT works

I see off-grid means , not using existing infrastructure, so it means the Victron Quattro is illegal in the City of Cape Town, if you use Eskom to Charge batteries https://resource.capetown.gov.za/documentcentre/Documents/Graphics and educational material/CCT-Energy-PV-Brochure.pdf

As far I understand, Grid Tied If you want to be Grid-Tied in the City of Cape town, you must have an approved grid -tied inverter from the City of Cape town example Victron Multiplus II Off-Grid If you want to use an off-grid inverter example Victron Quattro which is not on the approved inverter list, you can use it in City of Cape town because it will not be grid-tied
