Muchachos Posted October 16, 2020 Share Posted October 16, 2020 Does the Hexing HXE310-P meter allow reversing the meter if the Inverter is set into Grid Feed-In? Quote Link to comment Share on other sites More sharing options...
Louisvdw Posted October 16, 2020 Share Posted October 16, 2020 Normally when you apply to do grid feedback they will come and install a new bidirectional meter. I'm not sure if this one will be, but the bi-dir are more expensive meters, and I doubt those will be installed by default. Quote Link to comment Share on other sites More sharing options...
Tariq Posted October 16, 2020 Share Posted October 16, 2020 In the CoCT, they charge around R12,000 for a bi-directional meter Quote Link to comment Share on other sites More sharing options...

My HXE310-P meter went into tamper mode because of accidental feed-in... Called CoJ and the guys that came to check didn't know what is happening or how to sort it out even though I told them what has happened Still waiting for a new meter or hexing keypad that can supposedly fix it.

Bobster. Posted October 19, 2020 Share Posted October 19, 2020 On 2020/10/16 at 11:23 PM, Muchachos said: What rate does CoJ offer for grid feed-in? The proposed tariff for 2020/1, for residential properties who are net consumers and who sell "spare" power of less than 1 MW/h per month is 57.34 c. Plus you can't be on prepaid, you must be on a TOU tariff, your equipment must meet COJ standards (which implies an inspection) and you will need a bidirectional meter to be installed at your expense. If you're on pre-paid then switching to TOU means about R600 of service fees each month. COJ have been trying to force through a flat rate component for pre-paid connections. Two years ago it was removed because, the then Mayor said, somebody had sneaked it in after council had signed off on the new tariffs structure (at least that's what he said). More recently it was properly proposed then removed as part of relief under the pandemic, but it's not off the table. It will be less than the post-paid and TOU customers pay (as it should be. Pre-paid users pay more per kw/h). The long term objective seems to be to eliminate the gap between pre-paid and post-paid, which seems silly to me. If I pay in advance then that's good for the city's cash flow and they should give me some sort of consideration for that. Fuenkli 1 Quote Link to comment Share on other sites More sharing options...
Muchachos Posted October 19, 2020 Author Share Posted October 19, 2020 Hmm. The bill currently has three items that I am not sure what they are for, namely Network Surcharge kWh, Service Charge and Network charge. There cost for these are R78,R147 and R596 respectively. Is the network charge the TOU? Quote Link to comment Share on other sites More sharing options...

This is why most domestic users should still be converting to prepaid even though the deal is not as good as it used to be. You pay more per kw/h, but lose several hundred rand a month in flat fees. It is expensive for a short period because you have to pay down the post-paid account whilst still feeding the meter for power you consume NOW. Also there may be a charge if they have to change the meter. But most people who do the math find they come out ahead in the long run.

The good news is that you are unlikely to have any problems with a grid-tied setup (this can sometimes result in low-power/short-duration feedback to the grid - causing some prepaid meters to trip). The bad news is that you are likely to be charged (i.e. units deducted) for any power that you feed back to the grid!

Tampering Proof detection by: • Meter Cover open detection and record • Meter terminal detection and record • Bypass (optional) • Large magnetic event(optional) Auxiliary Terminal for Energy Pulse Output(optional) A few years ago I accidentally opened the terminal cover on a pre-paid meter that went into tamper mode and I had to pay a call-out fee/fine for the municipality to switch it on again.

I've had City Power at my place to find out what's going on because I am not feeding the pre-paid. They didn't say anything, but for sure they know I have a solar system. It seems to me though, and as I've said before, that municipalities really don't want people feeding back into the grid. This may be to do with reduced revenues or with demand management. I don't know. I know it's not worth it for me to sell back to the City. Quote Link to comment Share on other sites More sharing options...
Muchachos Posted October 19, 2020 Author Share Posted October 19, 2020 Yeah, it does seem so. How does Tshwane handle feeding back into the Grid? Do they have the same tariff structure like CoJ? I was in their website and I could not download the tariff file. Quote Link to comment Share on other sites More sharing options...

According to thishttp://www.tshwane.gov.za/sites/Departments/Financial-Services/Financial-Documents/Approved MTREF/2019-20 electricity tariff part 1 - rectified schedule.pdf The city will pay you a whole 10c for every kw/h you export.

I am not familiar with the HXE310-P meter, but unless it's a bi-directional meter, it is highly likely you will be charged for pushing power back to the grid - as though you had used the same amount of power from the grid.

Muchachos Posted October 22, 2020 Author Share Posted October 22, 2020 https://www.dlms.com/product/Hexing-electric-HXE310-P_39 This link says it can do both unidirectional and bidirectional, I suppose it will need to be configured bidirectional for Grid Feed-in to work.

This article explains the current state of play in the Cityhttps://www.dailymaverick.co.za/article/2020-10-21-joburg-electricity-costs-spiral-as-city-suffers-covid-19-revenue-loss/ Quote If you live in the city, a conventional customer pays a service charge of R147.74 a month. “The charge is to recover some of the administrative and billing service costs,” says City Power spokesperson Isaac Mangena. In addition, you are billed a “capacity charge” of R435.24 a month. “The charge contributed to the cost of ensuring network availability on demand. City Power has to operate, repair and maintain the necessary electricity distribution network infrastructure in order to be able to supply,” says Mangena. There is a third tax on this – a “network surcharge” of R0.06/kWh for consumption over the basic 500kWh per month. Fuenkli 1 Quote Link to comment Share on other sites More sharing options...
