Build your system.

Solar panels for every DIY build — rigid monocrystalline for rooftops and ground mounts, flexible panels for vans and boats, and folding portable panels for power stations. We rate real-world output, build quality, and dollars per watt.

The brain between your panels and battery. MPPT controllers squeeze the most from your array; PWM controllers keep small builds cheap and simple. We cover sizing, features, and which ones are worth the money — like the Renogy Rover series.

Turn DC battery power into household AC. Pure sine wave inverters for sensitive electronics, and inverter/chargers that also manage shore power. We look at surge ratings, idle draw, and whether the wattage claim holds up.

Where your power lives. LiFePO4 (lithium iron phosphate) batteries for cycle life and depth of discharge, plus AGM and deep-cycle options. We weigh real usable capacity, BMS quality, and cost per usable kWh.

Plug-and-play power for camping, backup, and off-grid. Portable power stations and solar generators from EcoFlow, Jackery, Bluetti, and more. We report real usable capacity, recharge speed, and whether the inverter can actually run what you need.

12V systems are the heart of van, RV, and boat builds. DC-DC chargers, battery chargers and maintainers, 12V appliances, fans, and adapters. Practical low-voltage gear that keeps a mobile build running.

The stuff that ties a system together — and the part beginners under-buy. Solar cable and MC4 connectors, fuses and breakers, busbars, lugs, and crimpers. Correct wiring and protection are the difference between a safe build and a fire.

You can't manage what you can't measure. Battery monitors and shunts (like Victron's BMV series), inline meters, and Bluetooth monitoring. Know your true state of charge instead of guessing.

Matched bundles that take the guesswork out of a first build — panel, controller, and wiring sized to work together. A solid on-ramp for beginners, and a sanity check on what a system actually needs.
