Solar PCU LCD Display Messages Explained — Backup Mode, Mains Mode, Faults & Rotary Switch
The LCD on your Solar PCU is telling you something specific every time it shows a message. This guide decodes every display message — backup mode, mains mode, overload, battery low cut, high/low cut, solar mode — plus the three rotary switch positions and what they do.
How Solar Hybrid PCU MPPT Works: 4 Real Scenarios Every User Must Know
Most solar PCU users do not realise their system has four distinct operating modes. Kunwer Sachdev — who designed Solar PCUs at Su-Kam — explains each scenario: what triggers it, how the PCU manages solar, grid, and battery together, and why Scenario 4 is the one that actually reduces your electricity bill.
Solar Hybrid PCU Wiring & Earthing Guide: Wire Sizes, Panel Config & Safety Rules
Most solar PCU problems start with the wiring — undersized battery cable, wrong MCB type, missing earthing. This guide gives exact wire sizes for every circuit, solar panel series/parallel configuration, earthing rules under IS 3043, and the DC vs AC MCB distinction that prevents fires.
How to Connect Your Solar PCU to the App: Bluetooth and Wi-Fi Step-by-Step Guide
The BLE and Wi-Fi dongle turns your Solar PCU into a smart system you can monitor and control from your phone. This step-by-step guide covers both Bluetooth and Wi-Fi connection methods — dongle setup, scanning, pairing, OTP login, and adding your device for remote monitoring.

Frequently Asked Questions
What products does Su-vastika make?
Su-vastika manufactures lithium (LiFePO4) inverters and Home UPS, double-conversion Online UPS, heavy-duty IGBT UPS, solar hybrid PCUs, lithium battery banks, Battery Energy Storage Systems (BESS), and lift Emergency Rescue Devices (ERD) ranging from 850 VA to 500 KVA.
What is a lithium inverter and how is it different from a normal inverter?
A lithium inverter is a power-backup unit that pairs an inverter with a built-in LiFePO4 lithium battery instead of a lead-acid battery. It charges faster, lasts up to 6000 cycles, needs no water topping or maintenance, runs cooler, and delivers far more usable backup in a lighter, smaller package.
What is a Battery Energy Storage System (BESS)?
A BESS stores grid or solar energy in large lithium battery banks and releases it during outages or peak-demand hours, replacing diesel generators. Su-vastika builds single- and three-phase BESS from 4 KVA to 100 KVA and has installed systems as large as 200 KVA, with a roadmap to 1 MW.
Where is Su-vastika located and where are the products made?
Su-vastika designs and manufactures its products in-house at Ghamroj, near Sohna Toll Plaza, Gurugram, Haryana 122102, India. The same site houses the factory and the R&D lab.
Does Su-vastika export, and to which countries?
Yes. Su-vastika serves India and exports to 30+ countries across Asia, Africa, and the Middle East, including the UAE, Nigeria, South Africa, Kenya, Bangladesh, Nepal, and Sri Lanka.
How long do Su-vastika LiFePO4 batteries last?
Su-vastika LiFePO4 battery banks are rated for around 6000 charge cycles with an intelligent Battery Management System (BMS) for safety and long life — many times the lifespan of conventional lead-acid batteries.
