Solar Invertors

ATMOSFERA presents a wide range of on-grid, hybrid and stand-alone inverters for photovoltaic power plants of the best world manufacturers.

ABB Company manufactures 1-phase and 3-phase on-grid photovoltaic inverters of various capacities both for household and commercial use.

All network inverters from ABB have the transformer-free topology and generate the output alternating current of high quality. The inverters are characterized by stably high KPI in practically full ranges of input voltage and output load.

All on-grid inverters of ABB have the IP67 protection and may be installed outdoors.

One phase on-grid inverters ABB with capacity of 3-6 kW are designed for use at not large households.

Two individual MPP-trackers allow connecting 2 differently oriented fields of PV modules, located, for example, on different slopes of roof, to the inverter.

The efficiency of inverters’ transformation reaches 96.8%.

3 phase inverters ABB with capacity of 5.8-12.5 kW are designed for connection of “feed-in tariff” for households. These household solar inverters combine all capabilities of ABB inverters for commercial use: compatibility with remote monitoring and control systems, ease of installation, high performance and KPI at the level of up to 98%.

TRIO-5.8/7.5/8.5-TL-OUTD inverters are compatible with external environmental sensors, wire and wireless monitoring modules may be connected to them, and you can control the operation of photovoltaic plants, based on these inverters, both by computer and smartphone.

The series of 3 phase on-grid inverters from ABB, in addition to not large household devices, also includes the models for industrial use with capacity of 10-33 kW. The high transformation ratio (KPI of inverters) – up to 98.2% – makes them optimal for use at solar power plants that operate due to private or industrial “feed-in tariff”. The inverters are characterized by stably high KPI in almost full range of voltages at photo modules.

Thanks to two individual MPPT-trackers, the industrial inverters with capacity of 20 and 27.6 kW can operate with 2 differently oriented fields of photovoltaic modules.

The inverters do not contain any electrolytic condensers that make them more durable and reliable.

The ultra budget inverters with capacity of 0.9 kVA and 1.5 kVA may operate both with solar panels (with additional charge controller) and without them in the mode of household UPS. The inverters can operate in two modes of voltage stabilization – 180V-260V and 100V-300V – depending on users, connected to it. The mode of voltage stabilization of 100V-300V is designed to feed the users that are not particular about quality of electric energy, allows using less the charge of accumulator battery and increasing their service life.

Dutch company Victron Energy B.V. is specialized in manufacture of equipment and components for stand-alone energy systems for energy supply of industrial and residential facilities, sea and land transport, as well as photovoltaic systems. The technical solutions by Victron Energy are characterized by modular principle of construction, flexibility and scalability. The great experience in creation of marine and transport solutions allowed the company adding the highest reliability and perfect quality of assembly to the equipment for household and industrial segments.

Stand-alone solar inverters Victron Energy from series EasySolar are equipped with one or two built-in solar MPPT-charge controllers; as well they can charge the batteries from public power grid, transforming the alternating current in the wide range of voltages and frequencies. Protection of charge controller against short current, overload, overvoltage and undervoltage of batteries, overheating.

Stand-alone inverters Victron Energy from series Quattro have 2 stand-alone inputs AC and can charge the batteries from public power grid or from the additional source (generator), transforming the alternating current in the wide range of voltages and frequencies. The function of automatic load transfer (ALT) allows automatically switching over the network to the electric power supply from generator. 2 stand-alone outputs AC allow connecting 2 users of different type with various priorities for electric power supply to the inverter. For example, inverter Quattro during 20 milliseconds will turn off the users of the second output AC and switch over the electric power supply of the first top-priority output to supply from batteries. At full charge of accumulator, Quattro will redirect the excessive generation from PV modules to the public power grid for sale due to “feed-in tariff”.
In order to increase the total capacity of the system to 60 kVA you can connect up to 6 inverters Quattro in parallel.
The built-in protection against short current, overload, overvoltage and undervoltage of batteries, overheating.
The inverter is equipped with communication port VE.Bus for parallel and 3 phase connection, remote monitoring, remote control and system integration.

Multifunctional inverters MultiPlus from Victron Energy can charge the accumulator park with voltage of 48V from external sources, such as generators and solar power plants, transform the direct current from batteries into alternating current with pure sinusoid, as well as, in the mode of overload, it can conduct the alternating current from public power grid with capacity of up to 10 kW through itself. Two available outputs of alternating current allows energizing two types of users: critically significant users that require the uninterruptible power supply using accumulator batteries, as well as other users, which electric power supply is carried out only if there is the incoming electric power supply. In case of shutdown of electric power supply from public power grid inverters MultiPlus during 20 milliseconds automatically switch over to the mode of uninterruptible power source.
Up to 6 inverters MultiPlus may be connected in parallel in order to receive the larger capacity, forming one- or three-phase power grid with capacity of up to 75 kW (90 kVA).
While operating the external generator or the public power grid with limited capacity inverter MultiPlus allows establishing the maximum capacity limit for alternating current users in order to exclude the overload of external sources.
Serving the users in the mode of short-term peak demands, the inverter can compensate such peaks using the charge of accumulator batteries without overloading the external sources.
Further “sags” in demands will be used to restore the charge of batteries.
At full charge of accumulator, MultiPlus will redirect the excessive generation from PV modules to the public power grid for sale due to “feed-in tariff”.
