i wonder what the real reason was why the CoCT has changed your existing prepaid meter . I am not aware of any one way prepaid meters who credit you (spinning backward) when you feed in.

yes. As long as it is a prepaid meter. And as @Tariqmentioned, the CoCT exchanges an old spinning with a prepaid meter free of charge when you register your system.

not necessarily. We have an option in the CoCT to remain on the normal tariffs and fees with a grid tie system if we agree not to feed in.

it was reported by @Weasel (see below) (from post "Goodwe vs others") The goodwe es is a brilliant machine. They fall a little short on software and they have had a fair share of firmware bugs. Build quality and component selection im sorry to say surpasses victron by quite a bit. Before im shot at dawn im a massive victron fanboy and to someone like me blue offers the best all round. But credit where its due. The hardware issues guys have with them are almost assuredly because of improper installation, Oversizing backup or high inductive loads. Bonding does happen, guy

it works (at least on my inverter. It is the old model with the serial number starting with a 3). The unlabeled (third) connection on the "back up" output is indeed bridging to neutral in islanding mode .

not only. I am sure that age plays an important role as well.

They look similar to the Shoto batteries. Are they all coming from the same company?

i don't think this is necessary. The outlets are positioned sufficiently high above the bottom. My tanks have been in operation for 5 years and i never had a problem with dirty water. Last year i checked and cleaned the first tank the rain water enters the system (the tanks are connected in series). There was only about 5mm of sediment at the bottom. The other (downstream) tanks did not even need cleaning. I also do not have filters on the in and outlets (except leaf strainers on the supply pipes).

when you separate the plumbing it is a good idea to do it with a change over system. This will allow you to quickly switch back to municipality supply if there is a problem with your rainwater system.

That is a big advantage . i have a similar set up. I positioned a small (2500 liter) tank at the top of the property. The tank is used to gravity feed the rainwater circuit of the house and garden. With this set up you only have to pump water once in a while (this is cheaper and works well with a PV system).

Good idea. Although it will not save you money. I wish CT would subsidize initiatives like yours. Your project will help the city and you will still be able to shower without a bucket during the next drought . CT gets about 400 liter rain/m^2/year. If you can afford it and have the space I would catch and store about have of that coming from your roof. In your case i would also catch the small stream. Although based on my experience (i have 40'000 liter storage) you will be able to fill the tanks easily with rainwater only. And as @Richard Mackayadvised, split the water supply in the house.

it would have to fall to about 50% of the current price.

yes you would get 365 cycles if you empty the battery completely every day. This is however almost impossible to achieve.

i agree that batteries (at the current price) are not saving you money. Another thing to remember is, that you will only achieve about 200 cycles/year. Assuming a life expectancy of 10 years that is only 2000 cycles. Batteries at the moment only make sense if you need them to bridge load shedding or if you are forced to live off grid (or if it is your hobby ).
