80A MPPT solar charge controller for 12V to 60V battery banks

The OutBack FLEXmax 80 turns more of your solar array into battery charge, up to 30% more than a non-MPPT controller. Its fan cooling holds the full 80A output in ambient temperatures up to 40°C, and one model suits 12, 24, 36, 48 or 60V battery banks.

Full power in the heat

Active cooling and thermal management keep the full 80A available up to 40°C ambient. Above that, output is reduced automatically to protect the unit
Note: for indoor installation or inside a weatherproof enclosure. It must not be exposed to rain or direct sunlight.

See what your array is doing

The built-in backlit screen shows live status and the last 128 days of performance, with no extra display needed.

FLEXmax 80 Main Features:

  • Up to 30% more from your array: a continuous, active maximum power point tracking (MPPT) algorithm keeps the array at its best operating point as conditions change.
  • One model for every battery voltage: the battery voltage is selected in the field at start-up.
  • Password protected settings: charge set points can be adjusted to suit your battery, then locked.
  • Automatic temperature compensation: charging adjusts to battery temperature when the optional remote temperature sensor (RTS) is fitted.
  • Programmable auxiliary output: can be set up for different control applications.
  • Works with OutBack system displays: program and monitor it remotely from a MATE3s, MATE3 or MATE2.

Quick Specs:

  • Part number: FM80-150VDC
  • Maximum output current: 80A at 40°C, adjustable current limit
  • Nominal battery voltage: 12, 24, 36, 48 or 60VDC (field selectable)
  • Maximum PV open circuit voltage: 150VDC absolute maximum (coldest conditions), 145VDC start-up and operating
  • Recommended maximum array (STC): 1000W at 12V, 2000W at 24V, 4000W at 48V, 5000W at 60V
  • Typical efficiency: 97.5% at 80A in a 48V system
  • Peak efficiency: 98.44% (60VDC input, 48V battery at 53.1VDC)
  • CEC weighted efficiency: 97.3% (at 48VDC)
  • Standby power consumption: less than 1W typical
  • Charge stages: bulk, absorption, float, silent, equalisation
  • Voltage set points: 13 to 80VDC, user adjustable
  • Temperature compensation: 5.0mV per °C per 2V cell, with optional RTS
  • Auxiliary output: 12VDC, 0.2A maximum, programmable
  • Display: 3.1in backlit LCD, 4 lines, 80 characters
  • Data logging: last 128 days
  • Network connection: RJ-45 with CAT5 cable
  • Operating temperature: -40°C to 60°C (power derated above 40°C)
  • Environmental rating: Indoor Type 1
  • Conduit knockouts: one 1in on the back, one 1in on the left side, two 1in on the bottom
  • Dimensions (h x w x d): 413 x 146 x 114 mm
  • Weight: 5.53kg
  • Certifications: ETL listed to UL1741, CSA C22.2 No. 107.1

When it comes to the installation of hardwired electrical products in Australia, it is important to be aware of the regulations and guidelines in place to ensure safety and compliance.
As per the Electrical Safety Act, installations operating at ELV (Extra Low Voltage) levels of 120 VDC and below can be installed by individuals with the necessary knowledge and skills.

However, it is crucial to note that installations operating above ELV levels require the expertise of licensed electricians and experienced installers. Products falling under this category are not suitable for DIY (Do-It-Yourself) installation and must be handled by professionals. Attempting to install such products without the proper qualifications can not only compromise performance but also invalidate any manufacturer's warranties. 

At Buzz Energy Systems, we recognise the importance of reliable and efficient installations that prioritise safety, performance and warranty compliance. Our team consists of qualified tradespeople and specialists who are equipped with the expertise required to handle complex electrical installations.

For installations that operate above ELV levels, we strongly advise against DIY installation. Instead, we recommend seeking professional assistance from licensed electricians and experienced installers to ensure the proper installation and optimal performance of such products.

When it comes to installing hardwired electrical products above ELV levels, rest assured that Buzz Energy Systems can provide the necessary qualified tradespeople and specialists. Our professional installation services guarantee compliance with regulations, the preservation of manufacturers warranties and most importantly, your safety.

Do not compromise on the installation of your hardwired electrical products. Trust Buzz Energy Systems for a professional and hassle-free experience.
