Split Phase Power Without the Grid-Tied Trap

Split Phase Power Without the Grid-Tied Trap

Most grid-tied solar systems go dark the moment the utility fails — that defeats the entire point of backup power. The Growatt ATS 5000T-ES gives you genuine 240V split phase output from your off-grid inverter, meaning your well pump, refrigerator, and standard household circuits stay running during any outage. At Off Grid Vault, every component we carry is vetted to work within a coherent system architecture — no mix-and-match guesswork. This transformer integrates directly with Growatt off-grid inverters, converting single-phase output into the split phase power your home actually uses. Built for durability and consistent 5000W delivery, it handles L1 and L2 loads simultaneously up to 5000VA.

Built-In Transformer for Clean 240V Output

Built-In Transformer for Clean 240V Output

The ATS 5000T-ES eliminates the need for a separate external transformer by integrating one directly into the unit. This simplifies your installation, reduces wiring complexity, and keeps your system clean. With a rated AC output of 240V and 5000W capacity, it delivers stable split phase power for standard US residential loads. The maximum combined L1-N and L2-N output is 5000VA, supporting simultaneous operation of multiple circuits. Keep in mind the maximum imbalance between L1 and L2 is 2500W — if your expected load split exceeds that threshold, pairing two units is the field-tested approach.

Engineered for Growatt Off-Grid Systems

Engineered for Growatt Off-Grid Systems

Designed specifically for Growatt off-grid inverters operating at 48V battery voltage, the ATS 5000T-ES handles a max PV input of 6000W and max MPPT operating voltage of 450VDC. With a max charging current of 100A, it supports robust solar charging alongside stable AC conversion. This is not a generic aftermarket add-on — it is the manufacturer-engineered component for turning your Growatt inverter into a full residential split phase power source. For your cabin, homestead, or backup system, it provides the grid-independent 240V output that standard household appliances and well pumps require.

Compatibility Check

Confirm your system meets these requirements before ordering.

  • System uses a Growatt off-grid inverter with ATS-ES support
  • Battery bank is 48V configuration
  • Combined L1 + L2 load does not exceed 5000W with no single leg over 2500W

“I was running a Growatt SPF 5000 and could not figure out why my well pump would not start. Turns out I needed split phase 240V — this transformer was the missing piece. Installed it in about an hour, and everything came alive. Off Grid Vault pointed me to the right unit after I described my system. No guessing, no returns, just the correct component.”

Frequently Asked Questions

If your Growatt inverter outputs single-phase power and you need to run standard 240V household loads like a well pump, dryer, or oven, then yes — this transformer converts that output into split phase 240V. Without it, those appliances will not operate. If you are only running 120V loads, you may not need it. Not sure? Contact Off Grid Vault for a free system design consultation and we will tell you exactly what your setup requires.
The ATS 5000T-ES supports a maximum imbalance of 2500W between L1 and L2. For example, you could run 1250W on L1 and 3750W on L2. If your expected load split exceeds 2500W imbalance, the manufacturer recommends purchasing two units. This is a hard spec limit — exceeding it risks tripping protection or damaging the transformer. If you are unsure about your load balance, our free system design consultation will calculate your exact L1/L2 distribution before you buy.
The ATS 5000T-ES is engineered specifically for Growatt off-grid inverters. While the electrical principles are standard, we cannot guarantee compatibility or performance with inverters from other manufacturers. Using it outside its intended system risks mismatched voltages, communication errors, or potential damage. At Off Grid Vault, we do not recommend mixing components across brands without verified compatibility. If you are running a non-Growatt inverter, contact us — we carry split phase transformers matched to other platforms including EG4, Sol-Ark, and Victron.
Yes. Every product on Off Grid Vault ships free, including this transformer. There are no minimum order thresholds and no surprise freight charges added at checkout. The $244.95 price you see is the total you pay. Unlike generic marketplace listings where shipping costs can add 15-20% to your order, we handle it. For a purpose-built component like this, straightforward pricing is part of the deal.
The Growatt ATS 5000T-ES carries the manufacturer's standard warranty. Off Grid Vault is an authorized dealer, which means warranty claims go through us — not through a ticket queue with a third-party seller. If something fails under normal use, you deal with people who understand off-grid systems, not a returns department reading from a script. Additionally, our 30-day performance guarantee covers uninstalled returns in original packaging if the unit does not meet its rated specifications.
Both. The ATS 5000T-ES works in any scenario where your Growatt off-grid inverter needs to supply 240V split phase power — whether that is a full-time off-grid cabin, a homestead seeking energy independence, or a backup system that keeps your home running during grid outages. It is not limited to one use case. If your system design calls for 240V split phase output from a compatible Growatt inverter, this transformer does the job regardless of how often you run it.
