Characteristics of the SAJ R5 Series 3-8kW Inverter
The SAJ R5 Series Inverter with 3-8kW output power is a small grid-connected inverter, single-phase and without a transformer, which is responsible for synchronizing with the electricity grid of the electricity company to contribute to the consumption that we have energy produced in real time by the solar panels.


SAJ's R5 Series range offers a very interesting access range to have a small self-consumption installation at a private and residential level. To its extremely attractive quality-price ratio, we add performance and production characteristics that are perfect for small powers, with characteristics far superior to the use of micro-inverters. This is the highest powered model available. Below there are more options with single-phase powers from up to 3000W with two MPPTs. There is a very staggered range with multiple options in which we will surely find a model that fits our energy requirements.


SAJ R5 Series grid tie inverters make up a wide range. The model that concerns us more specifically corresponds to the 3-8kW one. Below are the 7000, 6000, 5000, 4000, 3680 and 3000W options that can offer less production if we connect fewer panels for our direct solar self-consumption installation. Among the most notable characteristics of this model we could list the following:


- It has 2 internal MPPT regulators that, given the power of the inverter, are suitable for connecting the panels in two series.

- A wide operating voltage range that will allow us to make series with greater comfort and flexibility. The MPPT work between 90 and 550VDC. Thanks to this, the inverter can be started up with only 3 panels of 72 cells.

- IP65 protection level that will allow us to place the inverter outdoors without any problem.

- A compact size (429x418x177 mm) and a very light weight of only 18 kg so that one person can install the inverter on any surface.

- Control of power reduction to avoid discharge of excess production to the electrical network by means of a compatible wattmeter (sold separately).

- Integrated Wifi and RS232 communication, with App for IOS and Android to be monitored at all times

- Simple and visual interface to be able to control its operation or any type of error.


Applications and features of the SAJ R5 Series 3000W-8000W Inverter:
The SAJ R5 Series 3000W-8000W Inverter is a single phase grid tie inverter. For this reason, the SAJ R5 Series 3000W-8000W Inverter must necessarily work with solar panels and with the electrical network. All R5 Series models incorporate two MPPT regulators with an efficiency greater than 99.9%. It also incorporates IP65 protection and various communication protocols, both to be able to monitor its operation and to communicate with the power measurement wattmeter.


The lower connections of the SAJ R5 Series inverters are as follows:

R5 Series Inverter Connections

A - Panel disconnector.

B - Panel mc4 connectors.

C - Connection for RS485.

D - Connection for RS232(GPRS/WiFi/4G).

E - Terminal takes earth.

F - AC outlet

G - Decomposition valves


The SAJ R5 Series 3000W-8000W Inverter is an inverter that allows us to interconnect with the electrical grid without the need for batteries, which is why this type of installation is economical and very profitable in the long term, given its low acquisition cost, zero easy maintenance and commissioning.

For this system with the SAJ R5 Series 3000W-8000W Inverter to work properly, we will need a group of solar panels, grouped into one or two series that meet the voltage requirements of these inverter models. We must make sure that the connected panels deliver a voltage that is within the operating range of the inverter. These models in particular, their MPPTs operate between 90 and 550VDC and to start they need a minimum of 100VDC. This is achieved with only 3 panels of 60 or 72 cells placed in series.
