Axpert MKS 5kVA 48vDC Inverter 80A MPPT Parallel card included

This is a multi-functional inverter/charger, combining functions of an inverter, solar charger and battery charger to offer uninterruptible power support with portable size. Its comprehensive LCD display offers user-configurable and easy-accessible button operation such as battery charging current, AC/solar charger priority, and acceptable input voltage based on different applications.

AGM Battery

Voltage covers: 6V, 12V Capacity: From 7Ah to 250Ah Designed floating service life: 12 years @ 20 °C/68 °F.

Range summary

The solar series is designed for frequent cyclic charge and discharge applications under extreme environments. By combining the newly developed Nano Gel electrolyte with high-density paste, the solar range offers high recharge efficiency at very low charge current. The acid stratification is highly reduced by adding Nano Gel. This series is suited for energy storage for renewable energies such as PV, wind turbine power systems and CATV.

  • 12 years float life at 20°C
  • Up to 5 years design life at renewable energy applications according to IEC61427
  • Wide operating temperature range from -15°C to 60°C
  • Nano gel electrolyte eliminate the acid stratification and prolong cycle life
  • Round trip efficiency as high as 85%.
  • Thick positive flat plate design with high Tin low Calcium alloy and high-density paste
  • Low self-discharge rate and long shelf life (9 months at 25°C)
  • Excellent deep discharge recovery capability

Construction


  • Positive plate – Thick high Sn low Ca grid with high-density paste

  • 24 month workmanship guaranteed

This is an estimation of the cost and a general detail of installation, confirm the specifics with your installer.

We do have installers that we can refer depending on your location.

Do you install?

We do not install we only supply Solar products.

We can however help find you an installer, this depends on your location.

Simply ask us after you have ordered.

Can I expand the system?

You can increase the battery capacity.

If you want to add more solar panels you will are restricted by the inverter peak load.

You can modify the solar power kit and keep the same inverter in order to descrease the price.

Can I change some of the components?

Absolutely, you can customise any part of the system to suit your own specification.

Do you have a payment plan?

No we don’t provide credit, we highly recommend taking a personal or business loan from your bank in order to get the best rate.
