Battery-Backup Solar Hub

24-hour continuous solar aeration with battery backup

The Airmax SolarSeries Aeration System Battery Backup is the only true 24-hour off-grid pond aeration system in the ProPond catalog — a solar pond aerator with battery backup that never stops for sundown. Solar panel array charges a battery pack during daylight; the battery keeps the aeration compressor running through the night and through cloudy days. Continuous dissolved oxygen delivery to your pond even when the sun is not on the panel.

The reason 24-hour matters: fish and koi need continuous dissolved oxygen 24 hours per day. Daytime-only solar aeration (standard direct-drive solar) does not deliver oxygen overnight, and that is when dissolved oxygen crashes are most likely to happen. If you have livestock, koi, bass, or catfish in an off-grid pond, battery-backup solar is the correct answer over daytime-only solar.

Why buy battery-backup solar aeration

Four situations where 24-hour battery-backup solar beats daytime-only solar or trenched grid electric.

24H

24-hour dissolved O2

Continuous aeration through the night. Prevents overnight dissolved oxygen crashes that kill fish. Daytime-only solar cannot deliver this.

FISH

Fish pond safe

The correct answer for fish, koi, bass, or catfish ponds off-grid. Livestock ponds where dissolved oxygen matters overnight and during multi-day cloudy stretches.

$

Cheaper than trenching

Trenching electrical service to a remote pond typically costs $5,000-$15,000. Battery-backup solar at $8,200 is often cheaper AND eliminates monthly electricity cost forever.

☀

Multi-day cloud coverage

Battery bank rides through overcast days and stormy stretches without losing aeration. Direct-drive daytime-only solar loses aeration whenever the panel is not producing.

Battery-backup vs. daytime-only solar aeration

Three decision paths depending on your pond livestock and aeration timing needs.

Battery

Battery-Backup ($8,200)

Airmax SolarSeries with Battery Backup. Continuous 24-hour aeration for fish/koi/livestock ponds off-grid. Rides through overnight and cloudy days.

Direct

Daytime Direct-Drive ($5,800)

Airmax SolarSeries Direct Drive. Aerates only during daylight hours. Cheaper than battery-backup but no overnight coverage. Best for algae/weed control ponds without fish.

FISH
SAFE

Fish ponds need battery-backup, not daytime-only solar

If your off-grid pond holds fish, koi, or other livestock, daytime-only solar aeration is a fish-kill risk. Dissolved oxygen crashes typically happen overnight when photosynthesis stops. A pond that gets oxygenated all day and drops all night can lose fish in a single warm summer night. Battery-backup keeps the aerator running through the crash window. Call (470) 354-1969 if your pond has fish and you are choosing between solar options.

Battery-backup solar FAQs

Common questions on 24-hour off-grid pond aeration.

What is battery-backup solar aeration?

Solar panels charge a battery pack during daylight. The battery pack powers the aeration compressor continuously, including overnight and through cloudy days. Result: 24-hour continuous dissolved oxygen delivery to the pond without any grid electrical connection.

Why does 24-hour aeration matter?

Fish and koi need continuous dissolved oxygen. Overnight, photosynthesis stops but respiration continues, so dissolved oxygen typically drops. Warm summer nights are the most common time for oxygen crashes and fish kills. Daytime-only solar cannot prevent this. Battery-backup keeps oxygen delivery active through the danger window.

How long does the battery last overnight?

The Airmax SolarSeries Battery Backup is sized to run the aeration compressor 24 hours per cycle with a fully charged battery. Multi-day cloudy stretches (3-5 days) reduce charge cycles but typically still maintain aeration; extreme extended overcast periods (7+ days) may require compressor cycling. Contact us to spec for your specific climate.

Battery-backup vs. daytime-only solar: cost comparison?

Daytime-only (Airmax Direct Drive $5,800): cheaper up-front, no battery to replace over time. Best for algae/weed-control ponds without livestock.

Battery-backup ($8,200): $2,400 more up-front, plus periodic battery replacement (typically every 5-10 years). Required for fish/koi/livestock ponds.

How often do batteries need replacing?

Typical service life is 5-10 years depending on climate and cycling frequency. Batteries slowly lose capacity over time; when overnight runtime drops noticeably below spec, it is time for replacement. Call for replacement battery pricing.

How much sun does the panel need?

Standard 4-6 hours of direct sun per day averaged over the year. Works throughout the continental US. Panel needs clear south-facing exposure without shade from trees, buildings, or terrain. Plan panel location carefully before install.

How large a pond does this cover?

Sized for 1 to 3 acre residential/farm ponds at typical 8-12 foot depth. Larger ponds (3+ acre) may require multiple compressor units or supplemental aeration. Call (470) 354-1969 with your pond dimensions.

Can I install this myself?

Yes for most residential installs. Mount the solar panel on the included frame with south-facing exposure. Set the battery cabinet on a stable pad near the shore. Connect the compressor, route tubing to the pond, drop the bottom-set diffuser in the deepest area. No AC electrical wiring involved so no licensed electrician needed.

What warranty is included?

Airmax manufacturer warranty on compressor and system components. Solar panels typically carry a separate 5-25 year manufacturer warranty. Batteries have their own warranty period (typically 2-5 years). Pro Pond Supply handles claims as authorized dealer.

Is shipping really free?

Yes, free U.S. ground shipping. This system ships LTL freight with liftgate service due to size of solar panel and battery cabinet. Typical delivery 5-15 business days. Call (470) 354-1969 for current stock and ship date.
