Sofar Hybrid 20KTL-3PH

The Sofar Hybrid 20KTL consists of high efficiency energy resilience—providing a good back-up in case of grid outage. The model maximizes the energy independence through self-consumption. Thsofare maximum PV input power ranges up to 30000Wp (15000 Wp, 15000 Wp).

Working

This solar inverter model has maximum DC voltage of 1000V. It requires around 200V for the startup operation. The nominal DC voltage is 600V. Likewise, the full power voltage range of the MPPT module is 450 to 850 V. Some of the other characteristics of this solar inverter 2021 are;

  • The maximum input current of the module is 25A / 25A.
  • The maximum short current range is 30 / 30 Ampere.
  • The solar inverter consists of two MPP Trackers (two strings).

Battery Working

There are two battery input in the Sofar solar inverter 20KTL dedicated for lithium-ion. As being the best solar inverter in Pakistan, the charging strategy for the battery is self-adaption to BMS. The peak charging and discharging current duration of this solar inverter 2021 is 70Amps (35A, 35A), in 60 seconds. Other characteristics regarding battery input data are;

  • The solar inverter model uses CAN (RS485)>/td> as the communication interface.

Frequently Asked Questions

Do solar inverters go offline at night?

A solar inverter converts DC to AC, this means the appliances in the houses are provided normal current through the solar inverter. Thus, leaving the solar inverter on at night would not interrupt; settings of different devices (clocks, alarms, ovens etc.) If you plan to have continuous don’t set them to go offline.

How long does a solar inverter last?

The lifetime of a solar inverter mainly depends on the quality of inverter module, environment, and maintenance. The typical lifespan of an economical model is 10-12 years. These are some models that comes with up to 5 years warranty;
