Solar Inverters

A typical solar system consists of an inverter, batteries, battery charger, solar panels, solar charge controller (SCC) and the cables and protection equipment.

Solar Inverters use power electronics technology to convert Direct Current (DC) energy from batteries or photo-voltaic (PV) panels (the sun’s energy) into Alternating Current (AC) energy to power AC loads. This AC energy (e.g. 230V AC singly phase) can be utilised to power ordinary AC-powered equipment and appliances, or fed into the national electrical grid where permitted. Solar inverters are critical components in solar photovoltaic systems and are available in a variety of sizes and functions.
Some solar inverters have the solar charge controllers and battery chargers built-in. A solar charge controller such as a Maximum Power Point Tracker (MPPT), tracks the PV panel array’s output voltage and current to obtain maximum possible power from the PV array in any given environmental condition. While the battery charger controls both the charging and discharging of the batteries to enhance battery life.

Intelligent hybrid inverters for a complete solution

Rentech offers a range of solar inverters that
are classified into three main categories:

Stand-alone inverters used in isolated systems

Inverters draw DC energy from batteries charged by solar panels. The inverters also incorporate integral battery chargers to replenish battery energy from an AC source, if available.

Grid-tie inverters that match phase with a utility-supplied sine wave

For safety reasons, grid-tie inverters are designed to shut down automatically upon loss of utility supply. It does not provide backup power during utility outages.

Intelligent hybrid inverters for a complete solution

Inverters manage solar energy from photovoltaic arrays, battery storage and the utility grid, all of which are coupled directly to the unit. Rentech’s modern hybrid inverters incorporate all of the features needed to be used for grid-supported, stand-alone or backup applications. The inverters’ true function is self-consumption with the use of battery storage and to provide back-up power during grid failures.

On-off grid inverters that allow for export into the grid and/or off-grid operation

Inverters connected and synchronized to the utility supply that can also export energy into the utility supply, where permitted by the municipality or national service provider. Export can be limited to a selected power rating or to zero export where not permitted. When utility power fails, the inverter disconnects from the grid and continues to provide power to the off-grid load. Excess solar energy is exported on the AC import port to reduce power consumption from the utility and any excess over the local load can be exported to the utility, where permitted.

Rentech offers off-grid inverters from 12V up to 48V and 1kW up to 5kW, with some 5kW models that can be used in parallel for more power or 3 phase systems. Rentech also offers On/Off-grid battery hybrid inverters from 3kW single phase to 20kW 3 phase, with parallel capability, built in remote monitoring and matching lithium battery packs, as well as grid-tie string inverters from 6kW single phase to >100kW 3 phase.
