What Size Solar Inverter Do I Need? Sizing by Real Load
what size solar inverter you need is decided by the largest load it must run at once and the surge that load draws when it starts — not by the rating of your solar array. This guide sets out the sizing sequence, how much surge margin to allow for motors and compressors, when to accept clipping […]
Solar Inverter Connection Diagram: The Wiring Order and What Misses
A solar inverter connection diagram is the schematic that shows the order in which the array, the protection devices, the inverter, the battery and the loads connect — and the isolation and earthing that must sit between them. This guide walks through that order stage by stage, explains what each isolator and protective device is for, and […]
Maximum Power Point Tracking Inverter: How MPPT Actually Works
A maximum power point tracking inverter is an inverter that continuously searches for and holds the voltage at which its PV input delivers the most power, rather than forcing the array to a fixed voltage. This guide explains why that point moves, how a tracker finds it, what separates MPPT from simpler PWM control, and the voltage-window […]
Solar Panel Tilt Angle: How to Choose the Right Pitch
The solar panel tilt angle is the pitch at which a fixed array is set relative to horizontal, and it decides how much direct sun the glass catches across the year. This guide explains the latitude starting point, why the best annual angle is not the best winter angle, how orientation interacts with pitch, and what to […]
Solar Panel Mounting Brackets: Types, Loads and How to Choose
solar panel mounting brackets are the hardware that fix a PV module to a roof, a ground structure or a rail — and they are the components that decide whether the array stays where it was installed. This guide covers the main bracket families, the loads they actually have to carry, the material and corrosion choices, […]
Solar Panel Maintenance: What to Check, How Often and Why
solar panel maintenance is the routine of inspecting, cleaning and verifying a PV array so it keeps producing what it was designed to produce — and for most systems it is mostly inspection rather than repair. This guide sets out what to look at each season, how to decide whether cleaning is actually needed, how to […]
LiFePO4 Battery Temperature Range: Charging, Storage and Limits
The lifepo4 battery temperature range is the band of ambient and cell temperatures within which the battery will discharge, charge and hold its rated life — and the boundaries that matter most are on the charging side, not the discharging side. This guide explains the typical discharge and charge windows, why charging below freezing is the failure […]
Lithium Ion Cathode Materials: LFP, NMC and What Each One Means
lithium ion cathode materials are the compounds on the positive electrode that host lithium ions during charge and discharge, and the choice of cathode sets a cell’s nominal voltage, its energy density, its cycle life and much of its thermal behaviour. This guide explains the main cathode families you will meet in storage specifications — LFP, […]
Group 24 Deep Cycle Battery: Dimensions, Ratings and Where It Fits
A group 24 deep cycle battery is a BCI group size — a standard case dimension and terminal layout — that is the most compact of the three common deep-cycle sizes, built to be discharged and recharged repeatedly rather than to crank an engine. This guide covers the dimensions you must check against a tight tray, the […]
Group 31 Deep Cycle Battery: Size, Amp Hours and Where It Fits
A group 31 deep cycle battery is a BCI group size — a standard case dimension and terminal layout — that carries more capacity than group 24 or group 27 and is built to be discharged and recharged repeatedly rather than to crank an engine. This guide covers the dimensions you must measure against, the amp-hour and […]
