EnerDC MPPT solar charge controller 90V / 20A with display is available for purchase in increments of 1

Advanced MPPT real-time tracking algorithm of the EnerDC 90 | 20 solar charger

This controller allows you to charge a 12Vdc battery bank using standard 250-275Wp 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:

  • 250-275Wp PV modules with 60cells
  • 250-275Wp PV modules with 72 cells
  • Two or three 80-90Wp modules with 36cells connected in series or parallel

24Vdc battery

  • Two 250-275Wp modules with 60 cells each connected in series
  • Two 250-275Wp modules with 72 cells each connected in parallel
  • Three 80-90Wp modules with 36 cells each connected in series
