Planning a solar system

Stupid question.

If the system is grid tied how does this work in terms of when the system falls back on the grid? Will it deplete the batteries up to a certain charge and then switch over to the grid? For example if we have 10kW from 2 Hubble's at they are depleted by 3AM what happens then?

It will fall over to the grid, on the SunSynk and Deye super hybrid inverters you have a lot of control ito when what happens.

You can by example program the inverter to draw from grid between 2am and 7am should the SOC of the battery fall below 15% (just a random example). So if it drops to 15% at 6:30am it will draw from the grid from 6:30am onwards until 7am.

You can then set a new program that determines what happens after 7am

It will do whatever its programmed to do.
You can choose how it works.
 
Frack. Loot cancelled my order for the 2x Efergy Electricity Monitor Standard CT (13mm 90A) Sensor Clips after I had confirmed with them that their supplier had stock. 7 days after placing the order.

Anyone have an idea of any other reputable online sites that actually have stock?

Check Ellies.

I think they are the official distributor locally for efergy.
 
It's very early days yet, but it looks like I might have found a potential installer that would be willing to do an install in my little dorpie.
 
use geewiz they much more reliable. But I have just checked on their website and those clips (yeah I have 3 of them as I have 3 phase) are all sold out until April!! fml... clearly more people are checking their usage

if you dont want to wait, I see one chap selling his on gumtree for R1,500.

What? When I asked them they said they'd get some in February. *sobs* I ordered my E-Max from them and was very impressed by their service.
 
Would you also suggest 2 strings of 8 for 16 455w JA Solar Mono Perc Half Cell panels on a 8kW Sunsynk?

Even if it's -10 degrees, you would still be ok with 9 in series, 2 parallel strings on each MPPT for a total of 36 panels, so 19,440kWp (assuming perfect conditions of course). But you would need to take into account Max PV of the inverter which is 10.4kW, so 18 panels, 4x 4/5 in series, 2 parallel strings. This will put each MPPT at 215-268V, which is within MPPTs optimal operating range (125-425V).
