I got a quotation today from Energlaze on installing following: 10x peimar 300w allback panels 3kw 3000sph hybrid inverter 4.8kw battery storage zappi car charging point (free until 28th Feb) price breakdow as follows: 11,995 inc vat -3,100 grant net cost 8895 once i have EV purchased further grant of 600 e applied. that brings down over all solar panel system down to 8,295. So my question is: is this a good deal or is it a rip off, should i shop around for better deal? thanks in advance!

KCross wrote: » Are you sure about that? Sounds like an over enthusiastic salesman to me. To get that charge point grant you need to apply for it BEFORE you do any work and you dont get the grant unless you can prove you have an EV bought so I dont believe you can retrospectively apply for the grant.

These prices are all after grant. Cheaper panels (Peimar): 4kw with 2.4kwh battery - €4550 4kw with 4.8kwh battery - €5800 5kw with 2.4kwh battery - €6050 5kw with 4.8kwh battery - €7300 Premium panels (Solarwatt) 4kw with 2.4kwh battery - €6150 4kw with 4.8kwh battery - €7400 5kw with 2.4kwh battery - €7300 5kw with 4.8kwh battery - €8550 Battery and inverter are both by Growatt, 10 years warranty on inverter, 5 year on the battery. The Peimar panels are guaranteed for 20 years to retain minimum 80% capacity. The Solarwatt are guaranteed for 30 years for 87% capacity. The Solarwatt are also guaranteed against salt/corrosion. I do have a high usage, averaging about 11 units per day and 15 per night (night rate tariff). Have some heavy use stuff like electric car charging (usually overnight) and a 400l tropical fish tank 24/7. Average bi-monthly bill is about €170 in summer and €230 in winter. Thise prices also include immersion diverter (can be removed to drop the price by €450).

But during the winter that it can be charged on night rate and discharged during day rate. I think I found an MPPT Hybrid Inverter that would suit, Solis 5kw Hybrid Inverter RHI-5K-48es. See below snippet from the installation manual. What do you all think, it would help reduce payback time.Attachment not found. What do you all think, would it help much to reduce payback time?

Evd-Burner wrote: » As this particular unit also has a UPS function I had assumed the discharge time would be for providing power to the house and not the grid? I know a certain amount of the battery can be used as a reserve. Does anybody know how this charger would work with something like the Zappi charger? I have an electric car where I'd love the excess to also go to it also.
quentingargan wrote: » 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 threshold of 100 watts or more.

To turn on the immersion is no not going to take 1.5ke from the PV and another 1.5kw from the mains in order to power the 3kw switch? At that rate is the diverter not pointless I’d you are on night rate where you can charger the water at half rate anyway?
Evd-Burner wrote: » No the diverter has monitoring equipment and controls how much energy is diverted. So it only diverts what you would potentially send to the grid. So if you are generating 2kw and using 0.5kw then the diverter would send 1.5kw to the immersion.
Evd-Burner wrote: » Rolion, I take it that you have some sort of boost installed, if so do you ever get full tanks out of it or do you have to boost it?
rolion wrote: » For me is a bit different as i have the solar tubes as well,heating the 300l cylinder. Once the cylinder reaches 70 degress (from tubes or immersion),it switches off the diverter with "HotTank" warning. For a typical 2KW minimum installed array power,i am assuming in 8 months of the year's 12 months, you will have excess PV going to immersion OR to grid (less in cloudy days and in weekend) I am going offtopic here...sorry ! The main thermodynamic advantage of the immersion element is that the cold 13 degrees water in the bottom of the cylinder is getting "thermo kicked" to maybe 25-30 degrees by the PVs via immersion ellement. That "magic" boost makes the immersion viable and efficient as the main heating system (gas boiler via cylinder's integrated larger designed efficiency coil) has to work less to heat the water to over personally accepted 50ish degrees

rolion wrote: » ALSO,very important,is highly recommended to run a service call every year maybe oen hour just to check the system,even if you dont have to change any parts or fluid agents. Sort of a car NCT / DOE but for your own protection. Those solar tubes can reach hundreds of degrees while in operation,as below.
