PowerBox
A portable power distribution box that takes one feed and splits it into four weatherproof outlets, each on its own 15A breaker, all behind a 30mA GFCI-type main. A digital meter on the front counts the kilowatt-hours running through it. Brand new, and a simple way to run power on a job site, in a shop, at a campsite, or off an inverter or generator.

One feed in, four protected outlets out.
The PowerBox is a portable power distribution box. You feed it from one source, the grid, a generator, or the 120V output of an inverter, and it hands you four weatherproof outlets, each on its own 15A breaker. The whole box sits behind a 30mA earth-leakage main, the same kind of GFCI protection a wet-location outlet gives you, so a fault trips the box instead of a person. A digital meter on the front counts the kilowatt-hours that pass through.
Four breakered outlets
Four NEMA 5-20 outlets, each on its own 15A breaker. Trip one and the other three keep running, so you are not daisy-chaining power strips off a single cord.
GFCI-type main
A 30mA earth-leakage main protects the whole box. On a damp job site or out at a campsite, that is the difference between a tripped breaker and a shock.
Built-in kWh meter
The front meter counts the energy that passes through. Handy for sub-metering a shop, a shed, a rental, or a guest cabin, or just seeing what a tool actually draws.
Weatherproof build
An IP54 enclosure and IP44 flip-cap outlets keep rain and dust out. Screw it to a wall or grab the handle and take it with you.
Runs off your inverter
Feed it from an inverter and you get four protected, metered circuits straight off your battery bank, without wiring up a full sub-panel.
Wire it once
One cord in through the cable gland, four circuits out, all the protection built in. Land the feed once and it is ready wherever you set it down.
The PowerBox suits anywhere you need to split one power source into a few protected circuits: a job site, a workshop, a garage, a barn, an event, or a campsite power post. For the off-grid crowd, it turns the 120V output of an inverter or a generator into four metered, GFCI-protected outlets without building out a breaker panel.
It is 120V single-phase on 15A circuits, sized for tools, lights, pumps, chargers, and the usual plug-in loads. It is not a service panel and will not feed a whole house. Have a licensed electrician land the incoming feed, keep it inside its IP54 rating, and it will earn its keep for years.

Emporia Vue 3 Home Energy Monitor 16 Sensors
The Emporia Vue 3 wires into your electrical panel and shows where your power is actually going, from the whole-home total down to 16 individual circuits. It reads within about 2% of the utility meter and updates in near real time in the app, and it tracks solar production and net metering too. A simple way to see usage, spot waste, and watch a solar system without an expensive sub-meter.

Enphase IQ Combiner 5C
The IQ Combiner 5C is Enphase's all-in-one combiner panel. It holds up to four PV branch circuit breakers, hosts the IQ Gateway for system monitoring and grid-tie control, and provides the wiring point for the rest of the IQ stack. One box replaces a separate AC combiner, a separate revenue meter, and a separate monitoring gateway. The pre-wired internals are what save install time. Production CT clamps are factory-installed, the Gateway slot is hardened for indoor or outdoor mount (NEMA 3R rated), and the branch circuit positions are sized for the breakers Enphase microinverter strings need. Mount it adjacent to the main service panel, run AC out to the panel, run microinverter trunk cables in. For storage-equipped installs, the Combiner pairs with the IQ System Controller 3 (handles the backup/grid switch) and the IQ Battery 5P (modular storage). For monitoring-only installs, the Combiner alone with microinverters gets you per-module production data through the Enphase app. NEMA 3R outdoor mount, 5-year Enphase warranty.
