Hybrid Grid Tied Inverter with backup

[Tonye]

Hi All, it's been quite awhile since I have posted anything
Firstly may I wish all of you a Prosperous 2021

I have recently installed a Hybrid Grid tied inverter for a client and am so impressed, I thought I would share with you all

Firstly the specs & detail on the system

Kodak 4,6 Kw (Solis) Inverter fanless (Dual Mppt)
11 x 315W PV Panels
4 x US 2000 Pylontech Batteries
Auto Neutral/Earth switch
Combiner box with surge protection
Auto Change over switch



System Features
Export Power Management (EPM) with failsafe
Optimised Self consumption in priority (PV, Battery, Grid)
Reserve Battery for Load shedding (set at 50%, leaving 30% reserve for load shedding)
Optimal Battery charging (PV only or PV & Grid)

When Grid is available, both Essential & non essential loads are powered by PV, Batteries & Grid
When Grid fails, only essential loads are powered by PV & batteries

The geyser, Stove & oven are the non essential loads

The auto change over switch when grid fails has a transfer time of 50ms which provides uninterrupted power to essential loads

Basic wiring & power flow diagram


The online portal provides constant monitoring of the whole system
There is also an APP (Android & Ios) to monitor the system even when not at home

(see screen shot of App)



Client is extremely happy & only consuming between 2 & 4 Kwh from the grid
