How to crimp battery cable properly comes down to matched lugs, the right die and correct torque, according to NEC section 110.14, the ABYC E-11 marine wiring standard and crimp tool makers’ instructions. A battery bank can push hundreds of amps, so a solid crimp keeps that current flowing cool. Here’s the full process, plus […]
Solar panel specs printed on the back of every module tell you how much voltage and current it makes and how those numbers shift with heat and cold, and NEC sections 690.7 and 690.8 use them to set safe string voltage and wire sizes. Read them correctly and your charge controller or inverter stays within […]
Solar panel degradation per year is smaller than most people expect. NREL research on fielded systems has found a median loss of roughly 0.5% per year for crystalline silicon panels, and many newer panels are warranted to lose less. A panel that makes 400W today will still make most of that in 25 years. The […]
LiFePO4 vs lithium ion is a slightly misleading match-up, because LiFePO4 (lithium iron phosphate, or LFP) is itself a lithium-ion chemistry, and manufacturer datasheets show it trading some energy density for higher thermal stability and longer cycle ratings than the NMC and NCA cells used in phones, laptops and many EVs. For solar, RV and […]
How many solar panels do I need to power my house? You can answer that yourself in about 15 minutes with three inputs: your yearly kWh use, how much a kilowatt of panels produces at your address, and the wattage of the panels you’re quoted. Installers use the same math, plus a shade report. Step […]
The Lynx Class-T Power In is Victron’s answer to a long-running request from LiFePO4 users, especially in North America: a Lynx module that takes Class-T fuses. Class-T fuses are a common choice right at a lithium battery. Now you can fuse your battery strings inside the Lynx system instead of mounting separate fuse blocks. What […]
This home solar FAQ gives short, sourced answers to the 40 questions we see most, each linking to a deeper guide in our Home Solar series. Are solar panels worth it? That’s the question behind most solar threads on Reddit and homeowner forums. The honest answer depends on your electric rates, sun, roof and how […]
Update: Selling a house with leased solar panels is now routine in most solar markets, and homeowners have more ways than ever to handle it, from a simple lease transfer to a full buyout. Landowners with solar farm leases have a parallel option: selling future rent for a lump sum. This guide adds how mortgage […]
Is a solar panels on roof fire hazard worth worrying about? Rooftop PV fires are uncommon, and most trace back to installation faults rather than the panels themselves. Modern codes add protections for both homeowners and firefighters. Knowing what causes problems, and what good installs do differently, puts the risk in perspective. Electrical work can […]
The Tesla Powerwall 3 warranty is a good starting point for comparing home batteries, because every major brand words its warranty a little differently. Most cover around 10 years, but the details that matter are capacity retention (how much storage is guaranteed at the end) and any energy throughput cap that can end coverage early. […]
