Selected well pump backup
Keep water available during outages by sizing around the pump and pressure system first.

Texas Well Pump Battery Backup
Well pump backup is a surge and runtime problem first. We help Texas ranches, farms, and rural homes check pump HP, voltage, starting current, inverter size, battery count, and recharge plan before quoting hardware.
Best fit
Good pump-backup jobs have clear load data and a realistic runtime target.
Critical loads only
Add freezer, gate, Wi-Fi, cameras, and lights after the pump surge is understood.
Solar or generator support
For multi-day outages, confirm how the battery refills: solar, generator, or both.
Field support
We can support electricians with one-line concepts, settings, startup checks, and troubleshooting.
What we need before quoting
These details prevent undersized battery and inverter packages.
PumpHP, voltage, phase, starting current if known
Water systemPressure tank, storage tank, duty cycle, irrigation or home use
RuntimeHours of water availability needed during outage
Other loadsFreezer, gate, Wi-Fi, cameras, barn lights, controls
RechargeSolar, generator, grid-only, or future expansion
PaperworkCity/AHJ, utility, Oncor/PTO status, licensed electrician role
Pump details that change the system
Well pump backup is sized from the pump outward. The same battery bank can behave very differently depending on the motor, controls, and water system.
Single-phase or three-phase
Single-phase pumps are common on residential and ranch wells. Three-phase pumps are more common on larger agricultural, commercial, or high-flow systems and require a different electrical review.
Horsepower is only the first clue
1 HP, 2 HP, 3 HP, and 5 HP pumps can require very different startup support. We also check voltage, running amps, and any available locked-rotor or starting-current data.
Starting surge decides inverter fit
A pump can briefly demand several times its normal running power. The inverter must be reviewed for surge capability before a battery count or price is meaningful.
Control box and pressure system
Pressure tanks, control boxes, pressure switches, soft starters, and storage tanks all affect how often the pump starts and how hard the backup system has to work.
Simple field checklist
Send these items first. Photos are often faster than trying to decode old pump records by memory.

Battery and generator workflow
Many well-pump projects are better treated as a backup workflow than as a pure battery replacement for every outage scenario.
Battery handles selected water use
For short outages, a battery and inverter may keep the pump and small critical loads available without starting a generator every time the grid blinks.
Generator extends runtime
For longer outages, the generator can recharge the battery or support larger loads while the battery covers quieter selected-load windows.
Local field work stays local
Texas Ranch Energy supports hardware selection, documentation, one-line concepts, and startup settings. A qualified local installer handles site wiring and code work.
What not to assume
HP is not enough
A pump can need several times running power at startup. We size around surge, not just nameplate watts.
No unsupported UL9540 claim
Value hardware is not marketed as a certified ESS unless exact matching paperwork exists.
No permit promise
We help prepare product data and one-line/PTO packet items, but AHJ and utility approval stay with those authorities.
Well pump backup FAQ
These are the questions we try to answer before recommending a battery, inverter, or generator-assisted path.
How do I know if my pump is single-phase or three-phase?
Check the pump nameplate, control box, disconnect, or service panel. If the label is unclear, send photos before quoting. Phase matters because it affects inverter compatibility and field wiring.
Can you size the system from horsepower only?
No. Horsepower helps identify the rough class of the pump, but voltage, running amps, startup current, and control method decide whether the inverter can start the motor reliably.
Why does starting current matter so much?
Many pumps pull a short burst of current when the motor starts. If the inverter cannot support that surge, the system may fault even when the battery has enough stored energy.
Does a pressure tank help battery runtime?
It can. A properly working pressure tank can reduce short cycling and lower how often the pump starts. The actual benefit depends on tank size, pressure settings, leaks, and water-use pattern.
Should I choose battery-only or battery plus generator?
Battery-only can fit selected loads and shorter outages. Battery plus generator is usually better for long outages, high-horsepower pumps, or sites that also need other ranch loads during storms.
What should a customer send first?
Send pump nameplate photos, control box photos, pump HP, voltage, phase if known, ZIP code, desired runtime, existing generator or solar details, and the list of other loads that must stay on.
Request a well pump backup review
Send pump HP, voltage, ZIP, desired runtime, other loads, and whether you already have an electrician.
- We check whether the project fits battery backup.
- We suggest value hardware, certified ESS, or a generator/solar hybrid path when appropriate.
- You get a quote path before hardware payment.
Best starting point
Use the quote form and include a photo of the pump nameplate if available.
