Inverter Topologies

Understanding the various inverters and it’s building blocks.

Inverter

The standard inverter uses a DC storage medium (typically a battery) and inverts the low-voltage DC power to AC power. An external method of charging is required.

Inverter-Charger

The Inverter-charger is a standard inverter with a built-in AC charger and ATS (Automatic Transfer Switch). This enables the inverter to charge the batteries when grid power is available, and automatically switch to inverter mode once the grid falls away. Transfer times are in the order of 10 to 20ms and no interruption in power supply is noticeable. This is typically used in UPS applications.

Bi-Directional Inverter-Charger

A Bi-Directional Inverter-Charger can take excess power on the load side (usually provided by an external, grid-tie inverter, and feed it back into the inverter to charge the battery. The advantage is that the MPPT charging from the solar is done at very high voltages, which improves overall efficiency.

Systems like these can also be configured to feed back into the grid. In case of grid feed applications, S1 will automatically open when the grid falls away to prevent grid-feed and accidental shock.

There are different definitions of a Hybrid Inverter, but Sunray views it as any Inverter-Charger that has a built-in Solar charger. This can either be a MPPT or PWM charger, and is usually accompanied by smart power management that intelligently switches between solar and grid for battery charging. These are very popular in off-grid applications.

On-Grid Inverters

This wide grouping of inverters refers to any unit that can synchronize its inverted power (either from a battery inverter or solar inverter) to the incoming utility power. This is a requirement for grid feedback, net-metering, self consumption and mini-grids.

Hybrid Grid-Tie Inverter-Charger

This is the same as a standard Hybrid Inverter Charger, with the addition that the output of the inverter is synchronized with the grid, and feed back into the grid. This is a very cost effective mini grid solution.

Bi-Directional Hybrid Inverter-Charger

As with the Hybrid Grid-Tie Inverter-Charger, this unit feeds back into the grid, but the method of grid-tie is through a high voltage Grid-Tie solar charger, which has a higher efficiency and is more sophisticated than the battery-grid-tie-inverter. This system has it all: Backup, self consumption, Grid feed-in, smart battery management, smart load management, smart metering, comprehensive monitoring and a plethora of settings and options.

Grid-Tie Inverter

SMA
A Grid tie inverter uses a high PV voltage and inverts directly to AC power, which has an extremely high conversion efficiency. This AC power is synchronized with the input power from the grid and is used for self-consumption. Systems like this was developed for countries with a very reliable grid where net-metering or grid feed-in is allowed. In such a case, the grid would act as the storage medium. Grid-tie inverters can also be used in combination with other battery based systems in mini-grid applications.

PSW Hybrid Inverter/Charger – Kodak

back to top

Description

The KODAK off-grid inverter range is fully compatible with Pylontech and is a powerful combination for reliablydelivering energy to an off-grid or end-of-line supply. The inverter can prioritise how it uses power from the differentsupply sources to maximise the use of solar generation and energy storage, all while ensuring seamless provision ofpower to important loads.
A reliable combination of intelligent KODAK charger inverter with powerhouse Pylontech is particularly important formitigating the effects of load shedding. Load shedding is the radical practice of shutting off whole districts for severalhours to reduce the peak load to within available capacity. It has been common in South Africa and lately inZimbabwe. A correctly specified KODAK with Pylontech system will provide energy security to a home.

Topology: Inverter-Charger

Features

The inverters are split into three models: the VMIII, the MKSII and the King. This document focuses on the VMIII andKing models because of their built-in battery BMS communication.
The KODAK models have different features and capacities which should be understood when choosing the mostappropriate product for your installation. A chart on the next page compares some of the important features of theseKODAK inverters.
