Step-by-Step Guide for Remote Monitoring Setup for Lithium-ion Battery
Step-by-Step Guide for Remote Monitoring of a Lithium Battery via External GSM Card 1. Understand System Components & Requirements: BMS (Battery Management System): Manages battery parameters (voltage, current, temperature, cycles, alerts). OBD Interface: Connects to the BMS for data extraction and programming (e.g., CAN bus, SAE J1939 protocols). GSM Module: Enables cellular communication (e.g., SIM800C, Quentel modules) […]
How to Install a Solar Hybrid PCU: Complete Guide — Wiring, Safety & LED Indicators
A Solar PCU installed incorrectly underperforms or fails — no matter how good the unit. This complete guide covers wire sizing, safety rules, panel configuration, the installation diagram, and every front panel LED explained. By Kunwer Sachdev, who designed these systems at Su-Kam.
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.
What is Solar Power Conditioning Unit (PCU)
A Solar PCU (Power Conditioning Unit) is a critical component in solar energy systems that combines multiple functions to efficiently manage, and condition power generated by solar panels. It acts as the “brain” of a solar setup, integrating an inverter, charge controller. Here’s a breakdown of its role and importance: What Does a Solar PCU Do? DC-to-AC Conversion (Inverter […]

Backup and protection for VRF system for Cooling
When considering backup solutions for advanced HVAC systems like Variable Refrigerant Flow (VRF) systems, https://www.shareddocs.com/hvac/docs/1001/Public/0B/04-581067-01.pdf it’s important to understand that “backup” can refer to several different scenarios: Power Outages: In the event of a power outage, the entire VRF system will cease to function. Therefore, backup power solutions like 3 Phase Lithium UPS or Battery […]
Load calculation formulae is different for Tubular and Lithium battery Inverter/UPS
Difference Between Backup Time of Lithium-Based Batteries and Tubular Lead-Acid Batteries: Formulae and Why Lithium Requires Smaller Size Batteries When designing a backup power system, understanding the backup time and capacity of batteries is crucial. Lithium-based batteries (such as Lithium-Ion or LiFePO4) and Tubular Lead-Acid batteries are two popular choices, but they differ significantly in […]
How to calculate Load chart of a Lithium Inverter/UPS
The load chart calculations become different if the INVERTER/UPS is installed with Lithium-ion or Lithium LifePO4 battery or Tubular Lead Acid battery as the TUBULAR LEAD ACID BATTERY has the capacity of C20 or C10 maximum which makes a big difference in the calculations of time. https://suvastika.com/load-calculation-formulae-is-different-for-tubular-and-lithium-battery-inverter-ups/ When calculating the load chart for an inverter with […]
Importance of DC push Surge Delay Switch
