Core Power Plays

The specs and strengths that make it shine.

Discussion on solar panel efficiency

“the efficiency of a solar panel is like 15%-20%. So he is taking an 80% loss.”➕

“Can Solar and battery eliminate the need for a utility provider?”➕

“It is certainly possible to power a home with just solar and batteries.”➕

“most full grid off-solar people will include a small gas/diesel/natural gas generator.”➕

Discussion on solar backup and battery necessity

“Can a house run entirely on solar if power is shut off?”➕

“For best results you'll be needing batteries, too.”➕

“Solar will shut off without batteries.”➕

“Most solar inverters will not work off grid without batteries.”➕

Discussion about grounding solar panel systems

“Hope that helps, best of luck to your uncle with his new installation.”➕

“Don't skimp on buying modern GFCI+AFCI circuit breakers for the AC panel. They are life-saving devices.”➕

“In my opinion and experience, you should have both in a system.”➕

Discussion on battery management and dump loads

“the solar panels are sitting there doing nothing at that point.”➕

“My dump load is actually my air conditioner, because it means the AC kicks on right around peak production time.”➕

Speculation about energy production and usage

“Does it just go to waste, disappearing into thin air, or are the solar panels damaged?”➕

“Sort of! This is why people implement 'dump loads' to kick on when their other uses are not using all of the potential energy harvested.”➕

Discussion on solar panel functionality during outages

“I’m happy to live with power just during the day during an outage.”➕

“Batteries end up being the solution that buffers all of that.”➕

“to me it’s half the system”➕

“It’s not a mess, it works amazingly well.”➕

Discussion on using solar with limited sunlight

“I am thinking of using a solar system (solar batteries) with a generator to kick on & re-charge the batteries when they get to a low enough level.”➕

“If you aren't getting much sun, solar really doesn't make a lot of sense.”➕

“even SOME solar input will help keep the batteries topped off when the property is unoccupied.”➕

Speculation on solar panel efficiency and energy production

“I easily have 20A of excess, plenty to charge with margin.”➕

“the equipment is capable of much more than 30%.”➕

Hidden Hero Hacks

Unexpected tricks and side‑door uses you’ll love.

Humorous references to solar setup challenges

“The remainder is 3% good natured video game trash talking and 2% Weaponized-grade Dad Jokes.”➕

Humorous references to unconventional uses of excess power

“I’m imagining that in the use case described there would be two thermostats.”➕

“You can use the extra power to run really bright lights above the solar panels to generate MORE power.”➕

Discussion on the feasibility of using solar for whole-house backup power

“Actually the real problem is that prices are coming down so quickly that buying anything right now is almost certainly going to be 'overpaying.'”➕

Buyer’s Cheat Sheet

What to check before you click ‘Add to Cart.’

Speculation about the student's charging intentions

“how do we know the student wants to charge his phone later? Maybe he wants to charge lappy later?”➕

Recommendations for improving solar setups

“I would recommend getting the eg4 brand inverter with the same output.”➕

“The only thing I would change on this is to double the battery capacity.”➕

Debate on the necessity of battery backups for solar systems

“it just made more sense to get as much solar panels as I could.”➕

“it seems silly to keep arguing the point when OP even thanked jj for the explanation.”➕

“There are tons of grid-tied systems without batteries.”➕

“Most people with solar installed do not have the kinds of batteries we’re talking about here.”➕

Recommendations for solar system components

“fyi bad reviews if you don't have lots of power, hot water, etc, even if listed as rustic, primitive, etc.”➕

Discussion on solar panel charging for EVs

“I want to charge the van throughout the day when its parked up from the sun as direct from solar > van as possible!”➕

“If you add a battery into this setup it will work better.”➕

“A 3.6 kW solar system will likely be producing a lot of useful output below that threshold.”➕

“You would need an EVSE that can adjust its charge rate to match what is coming in from the solar panel inverter.”➕

Cautionary Callouts

Know the pitfalls before they catch you off guard.

Humorous references to charging devices

“He forgot to plug the charger”➕

“Does he also plug a power strip into itself, and wonder why the other items plugged in won’t turn on?”➕

“Hey McFly you bojo! Hoverboards don’t work on water. Unless you’ve got POWERRR.”➕

General appreciation for hybrid inverters

“big appreciation for the new hybrid inverters and how much they simplifying wiring.”➕

“If you're too worried about it you can plug them in every night and you'll be fine.”➕

“I cannot imagine not having two separate plugs at a minimum.”➕

“We have three EVs and three chargers, plus a 14-50 to use as a backup should one of the others die.”➕

Comments on generator annoyance and efficiency

“A generator is a pain to run and annoying to hear.”➕

“Let’s just say for the sake of math you want to max out a 48 volt 100 amp charge controller.”➕

Discussion about solar backup systems and their limitations

“Curious what happens when the utility power goes out and you have solar but no battery.”➕

“In other words, you won't have power during a blackout.”➕

“Your solar system isn't strong enough to run five houses worth of air conditioning and refrigerators.”➕

“Off grid meaning you have either batteries, or self islanding with Enphase IQ8s that allow sunlight backup that might run one outlet if there's enough sunshine.”➕

General interest in solar technology advancements

“Enphase switches my house over to battery power so fast the lights don't flicker.”➕
