Frelit FE-1.1S1 1100 W Single Phase String On Grid Solar Inverter

Frelit FE-1.1S1 On-Grid Solar Inverter Overview

Solar panels produce direct current, but everything in a building runs on alternating current. The inverter sits between the two and converts it. The Frelit FE-1.1S1 1100 W Single Phase String On Grid Solar Inverter takes DC from a panel string and feeds 1100 W of usable AC into a single phase supply. As a grid-tied inverter, it works alongside the mains rather than replacing it, so whatever the panels generate offsets what you would otherwise draw from the utility. It suits small rooftop installations on homes, shops and small offices. Frelit manufactures it in India.

Smart Features for Efficient Solar Power Generation

• Peak conversion efficiency of 97.3 per cent, so very little generation is lost in conversion

• Accepts up to 1350 W of PV input against 1100 W rated output, allowing panels to be oversized

• Maximum PV input voltage of 550 V with 18 A maximum input current

• Single MPPT tracker that adjusts continuously to keep the string at its best operating point

• WiFi and RS485 communication for remote monitoring of generation data

• Wide output range of 140 to 290 V, useful where grid voltage fluctuates

Technical Specifications

Suitable Solar Power Applications

• Residential rooftop systems of around 1 kW on single phase supply

• Shops, clinics and small offices looking to cut daytime electricity bills

• Net metering installations where surplus generation feeds back to the grid

• Small extensions to an existing solar array on a separate string

Purchase the Frelit FE-1.1S1 1100 W Single Phase String On Grid Solar Inverter where the building has a reliable grid connection, and the aim is to reduce consumption rather than provide backup power.

Why the Frelit FE-1.1S1 Is an Efficient Grid-Tied Solution

At 97.3 per cent peak efficiency, the losses in conversion are small enough that panel placement and shading will affect your output far more than the inverter does. Built-in WiFi means you can check generation from a phone rather than walking to the unit. This built-in feature matters when something stops working and nobody notices for a fortnight. Installers and EPC contractors can buy the Frelit FE-1.1S1 1100 W Single Phase String On Grid Solar Inverter in bulk, with quotes available for ten or more units. Larger systems and three-phase options are available across the On Grid Solar Inverter range.

FAQs

Q1. What is on-grid solar inverter?

It converts panel DC into AC and feeds it into your mains supply. Solar covers what it can, and the grid makes up the rest.

Q2. What is a solar inverter string?

A string is a set of panels wired in series into one inverter input. This model takes a single string on one MPPT.

Q3. How many solar panels are in one string?

It depends on panel voltage. With a 550 V maximum input here, a typical rooftop string runs to a handful of panels. Your installer should calculate it.

Q4. Which is better, on-grid or off-grid?

On-grid costs less and suits areas with a steady supply. Off-grid needs batteries and makes sense where the grid is unreliable or absent.

Q5. What is the major disadvantage of a grid-tie inverter?

It shuts down during a power cut. This is a safety requirement, so it will not run your loads during an outage unless you add battery backup.
