InverterWise is an independent site about backup power. We cover inverters, batteries, UPS units, and home solar, and we explain them without the sales talk. What sets the site apart is who does the explaining: a working professional engineer, not a content mill.
The technical content is authored and reviewed by Engr. Syed Farrukh Anwar, a Registered Professional Electronics Engineer. The goal is simple. Give you real engineering answers, so you buy the right backup power once, at the right size, without wasting money.
We go deep on the engineering because backup power is genuinely technical. We also work hard to keep it readable. You do not need a degree to use the calculators or follow the guides. You get the same math and the same standards a professional would apply, put into plain language for a normal home.
About the author
Engr. Syed Farrukh Anwar is a Registered Professional Electronics Engineer with boots-on-the-ground experience across South Asia and the Middle East.

International engineering compliance
Our guidance is grounded in the standards professionals actually design to. Here is how the major electrical codes compare on the points that matter most for home backup power and solar.
| Technical feature | PEC (Pakistan) | DEWA / Trakhees (UAE) | NEC / NFPA 70 (USA) | IEC (International) |
|---|---|---|---|---|
| Primary code | PEC Standard 1987 | DEWA DRRG Standards | National Electrical Code | IEC 60364-7-712 |
| DC voltage limit | 1000V (residential) | 1000V / 1500V | 600V (res) / 1000V (comm) | Up to 1500V DC |
| Inverter standard | IEC 62109 / 61727 | DEWA approved list | UL 1741 / IEEE 1547 | IEC 62109-1 & 2 |
How the guides get written
Each guide starts from a real question. Someone wants to know if a lithium battery is worth the extra money. Someone else wants to know why their new inverter hums or why the compressor trips the system on startup. We work through the answer step by step and show the numbers behind it. Where a rule of thumb breaks down, we say so. Products and prices change over time, so when something goes out of date we update the page instead of leaving old advice sitting there.
Where the money comes from
The site is supported by advertising, and that is how it pays for itself. Ads never decide what we recommend, and nobody can pay for a better spot in a comparison. We do not take money to rank one brand over another. If that ever changes, this page will say so first.
