Domestic solar PV quotes 2018

Would know a few people interested.

Is the grant 60% of overall installation, whatever that costs OR €9300 towards a 6kWp inc battery?

They are assuming an installed price of €15,500 for 6kw with 4.5kwhrs of battery storage.

Looks like the sort of prices you'd get for putting solar on the Children's Hospital :rolleyes:

Hi All,

Battery working very nicely indeed, balancing out the peaks and troughs on a cloudy day.

Just wondering why it only takes in 500w even though generation is 3kw, is that a limit? Would a second battery double this?

Thanks,
Gary

Can you tell us what exactly your setup is?

That would help. Apologies.

3.3kw of panels + Ginlong 3.6kwh Hybrid Inverter + pylontech 2.4kwh battery

Do you have any telemetry for consumption vs export etc?

also your inverter, can it charge the battery at night?

Have some data here:

It actually looks like it went over 500w all right a couple of times?

Cant do screenshots as the ginlong site's graphs are still in chinese.

Looks like your installer set the max battery charge rate at 10A, meaning you only see 10A * 50V = 500W charging. This seems extremely conservative. Even with a single Pylontech you can charge / discharge it continuously at 25A (and 100A peak for just one minute). You can double that rate if you have two Pylontechs, etc.

Your inverter can discharge at 3kW, see the specs here:

I would ring the installer and ask them what the story is there.

Hi all,

So I’m 2 weeks in to my new PV system running , 4.2kw Solis 5kw inverter with 2.4kw battery and solar iboost diveter , all together including vat was 11,180euro. So far I’m very happy with its performance, my question is does anyone know of a better monitoring platform as the Ginlong app / web / solarmanpv monitoring has lots of bugs , system is running latest firmware but information is updated every 1min, I got solarmanpv to change this for me from 5min but still doesn’t update regularly and also information like battery percentage etc is sometimes not shown. Wonder is there any devices that would work with solis inverters etc or a better way of monitoring so I can automate usage when there is excess .

Thanks

What sort of port has it got on it?

Hi,

It has RS485 and also have the WiFi stick installed ,

It looks like people have done work on this before, for example: http://60chequersavenue.net/wordpress/2017/10/solar-and-stats/

As a matter of interest, can the app be used to make the unit discharge?

I hope you got the EUR3,800 grant, so a net cost to you of a bit over EUR7k?

Absolutely got the grant !

Hello everyone, I have been thinking of getting a 4kw system with a 2.1kw battery with the hotwater iboost also for the last 6 months. I have gotten two quotes before grant of €9400 & 9700 all included. I am in the Limerick Tipp border does anyone have recommendations of installers for me thanks ( can private pm if not allowed to mention companys in public). Thanks again.

quick question for ye tech guys.
What is the difference betweed grid tied and off grid hybrid systems? Ive heard that off grid systems are better. Is that so?

Ive been quoted for the following:
10x Denim 355Wp All-Black mono crystalline PV module
1x Solis 3.0 KW single phase hybrid grid tied string inverter
1x 20A AC isolator
1x 3.5 kWP + 1x 2.4 kWP Li-Ion pylontech battery pack
1x santon fireman switch

Off grid is for when your house has no connection to the grid and it is prohibitively expensive to get connected. Like a very remote cottage. Or the dwelling is only occupied now and then like a holiday home. Or you are a prepper, doom is coming and you want to be self-sufficient

Most people are better off with a grid tied system...

How much are you quoted for above system, before and after the grant?

9436 e before grant
potential grant 3450

Does the solar iboost work ok with the battery or does it see the battery as excess PV generation?

i'm thinking of getting this diverter if I picked it up cheap enough but won't bother if it drains the battery?

I have similiar set up with Pylontech battery but have 2 x 2.4kw batteries but even with the battery I expect to give the grid alot of Kwh from April to September.

Hi Niallers1, see the below reply from quentingargan when I asked something similar. Battery would not be depleted.

Nope - the discharge time is for exporting from batteries. Something you don't want to do.

I don't know about Zappi. It works with iBoost. The issue is the "export threshold" - the amount of power the clamp will allow to export before it kick in. On this unit, the threshold is 70 watts. The iBoost cuts in at about 100 watts, so it is fine and the battery takes priority. Other diversion units cut in at 50 watts, so the battery ends up filling the immersion. You want to be sure any diverter you use, heat or car charging, has a theshold of 100 watts or more.

As you can imagine, this works with the myenergi family of products too. PV should go to house first, then any excess to battery, then to car (Zappi), then to immersion (Eddi), any left overs then go to the grid

Water John

Can could definitely be called a priorities switch.

Can you please pm me number also please wexfordman

Just catching up on a few points further back on this.

Diverters will work OK as long as the clamp on the diverter is less sensitive than the clamp for the hybrid inverter. With Solar iBoost and Solis hybrid, this works OK, but I have heard of combinations where it doesn't. Solis sensitivity is about 70w and iboost about 100w so all good.

Someone else mentioned charge control on Pylon batteries being restricted to 10A. This is the BMS over-writing the inverter settings and happens when the batteries want to manage cell balancing. It will flip back to 25A per battery.

Hi All,

Anyone any suggestions for a suitable heater that would work when exporting excess, have a solar iboost doing the hot water but would like to see if I could benefit more with the excess generated ?

Thanks

Most excess will occur in warmer months so probably low likleyhood of needing a heater. (Unless you need heat for growing plants )

Sending excess to battery or hot water tank would be more useful.

You can use any domestic heater or storage heater. You will need to use a relay to redirect the surplus to the second heater. You need the coil of the relay powered via a thermostat.

Agree totally on reflection. Using solar for space heating is a waste. What a pity we dream up all these strategies to self-consume all the power. It would be much better of electricity providers were forced to buy our surplus power and preserve the primary energy value that electricity has. (it would be environmentally better to export your surplus electricity and use gas to heat your water).

They said they never saw more than 500W going into or out of the battery. Which means the max charge / discharge rates must have been set to 10A at the inverter, surely?
