Domestic solar PV quotes 2018

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.

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

Hi,

It has RS485 and also have the WiFi stick installed ,

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

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?

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?

5.85 kwp solar (18 panels)

12k b4 grant, 8,200 after grant.

Could you PM me the name of your installer? Thanks!

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.

Can could definitely be called a priorities switch.

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.

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?

I am told it happens for a while, but should be OK by now. The battery BMS will always overrule the firmware on the inverter (or it should) to ensure long battery life. It happens when batteries are cold, or if they go over 51V in the case of Pylon
