Opti-Solar Inverters: A Review

Updated: Dec 27, 2019

Opti-solar inverters are made by a Chinese company based in Taiwan. Opti is a relatively new entry into the Nigerian inverter market. It sold its first inverters in 2007. Their first project in Africa was in 2013. But they are gaining grounds among dealers and users. They make a wide range of inverters.


General Description

  • Opti inverters come in grey and black colours.

  • They are bulky and come in plastic and metal casings.

  • Opti inverters are made for ‘rugged’ physical and power environments.

Features

  1. Most Opti inverters are pure sine wave inverters. However, they also have modified sine wave inverters like the SP Junior Series. Learn about the differences between pure and modified sine wave inverters here.

  2. Like all pure sine wave inverters, appliances do not run with a continuous buzzing or humming sound.

  3. Opti inverters have UPS capabilities. Thus they are able to switch without the appliances turning off.

  4. They have battery protection features that protect the batteries from over-charge, deep-discharge and short-circuiting when the terminals are not properly placed during installation or during use.

  5. They also have technologies that protect appliances that use them from damage.

  6. Inverters with higher output capacities come with cooling fans to ensure that the inverters do not exceed maximum temperature safety limits.

  7. Most opti inverters come with in-built PMW or MPPT solar charge controllers. Read all about charge controllers here.

  8. Some opti inverters can be either placed on racks or mounted on walls. Some come with stands and other rollers to help with placement and movement.

  9. They can be connected in parallel or phases for greater output.

  10. They can be charged with either grid power or standby generators.

  11. Opti inverters are hybrid based inverters, meaning that they can serve either as off-grid or as solar inverters. Read all about hybrid inverters here.

  12. Except for the lower capacity inverters, opti inverters have cooling fans that help regulate the temperature of the inverter to prevent overheating.

  13. The SPR AVR Series has a battery temperature sensor that can sense the temperature of the batteries.

  14. Opti inverters have a relatively wide input range 100V-360V.

  15. Opti inverters have displays with audible alarms that inform the user of the state of the inverter.

  16. Depending on the needs of the appliance, opti inverters has isolated DC and AC output sockets. The charging voltage and output voltage can be preset into the inverter.

  17. The SP Initial Series has a USB communication port.

  18. They have an operation monitoring app supported by support Android and iOS over which 12 inverters can be connected and data shared.

Home, Factory and Office Integration

Opti inverters come in grey and black colours that are meant to complement both interior home, office and exterior factory designs. They are bulky and come in plastic and metal casings. They are sleek, compact and elegant. The hybrid range come with rollers for easy movement. Some of the available models can be fitted to walls saving ground space.


Warranty

Opti-solar offers a two-year replacement and refund warranty on its inverters at the distributor’s cost. Opti’s warranty covers defective parts. For “Out of Warranty Repair” of all other models, in addition to components costs, they charge a handling fee.
