EnerDC MPPT solar charge controller 90V / 40A with display

Advanced MPPT real-time tracking algorithm of the EnerDC 90 | 40 solar charger

This controller allows you to charge a 12Vdc battery bank using standard  up to 580Wp 60cells poly- or moncrystalline modules. The fast MPPT controller will improve energy harvest  by up to 10% compared to slower MPPT controllers.

Programmable options and auto 12/24V recognition

You can choose from two standard battery types - GEL and Liquid. Also, you can set a night-light function or low-disconnect voltage

LCD display with many features

Read real-time PV voltage, PV current, Battery voltage, Battery current or check historic data.

Four-steps charging algorithm

Ensure a reliable, fast and safe charging with the four-steps charging algorithm.

Many protections against various treats

Protections against: PV over current, PV short circuit, PV reverse polarity, Battery reverse polarity, Batery overvoltage, Battery deep discharge, Load short circuit, Load over current .

Load output

Over-discharge of the battery can be prevented by connecting all loads to the load output (except for inverters). The load output will disconnect the load when the battery has been discharged to a pre-set voltage.

Day/night timing

You can use this controller in street-lighting applications. It can automatically start a connected load (lights) at sunset and it can stop them at sunrise, or you can set the working hours of the lights during the night.

Suitable modules

A single controller can be used in various PV-configurations. Below are the most frequently-used ones. Several controllers can work in parallel.

12Vdc battery

• 250-520Wp PV modules with 60cells;
• 250-520Wp PV modules with Voc < 80V;
• Two-three 80-150Wp modules with 36cells connected in series or parallel

24Vdc battery

• Two 250-580Wp modules with with Voc < 80V each connected in parallel;
• Two-three 80-150Wp modules with 36 cells each connected in series.
