Reliable Split Phase Power for Your Off-Grid System

The Growatt ATS 5000T-ES delivers field-tested split phase conversion for your off-grid setup, producing 240V output from Growatt inverters. With a built-in transformer and 5000VA combined L1-N and L2-N output, it handles residential and small commercial applications. Keep in mind the maximum imbalance between L1 and L2 is 2500W. A grid-independent build starts with components that actually work together, and this transformer is built-to-survive the demands of daily off-grid power delivery.

Eliminate Voltage Imbalance In Your Off-Grid System

Most off-grid builders discover too late that their inverter cannot deliver clean 240V split phase without the right transformer — leading to tripped breakers, damaged appliances, or an L1/L2 imbalance that cripples your whole setup. The Growatt ATS 5000T-ES solves this with a built-in transformer engineered specifically for Growatt off-grid inverters. At Off Grid Vault, every component we carry is pre-vetted for compatibility with your system architecture. No mix-and-match guesswork — this transformer speaks the same protocol as your inverter, delivering 5000VA across L1 and L2 without the imbalance problems that plague pieced-together setups.

Power Your Entire Home On 240V

Power Your Entire Home On 240V

Standard US homes run on split phase 240V — your well pump, dryer, and HVAC compressor all need it. The ATS 5000T-ES delivers a rated 240V AC output from your 48V battery bank, handling up to 6000W of PV input through your Growatt inverter. With a maximum charging current of 100A and MPPT operating voltage up to 450VDC, this transformer integrates into your existing solar array without requiring a complete system redesign. It is the off-grid proven component that bridges your DC battery storage to the AC loads your household actually runs.

Know Your Load Limits Before You Build

Know Your Load Limits Before You Build

The ATS 5000T-ES supports a combined L1-N and L2-N output of 5000VA with a maximum imbalance of 2500W between legs — for example, 1250W on L1 and 3750W on L2. If your projected loads exceed this split, you need two units. This is the kind of specific, honest specification that big-box retailers never mention. At Off Grid Vault, we give you the real numbers upfront so you can size your system correctly the first time — no surprises three months after installation when your well pump and refrigerator refuse to run simultaneously.

Compatibility Check

Confirm this transformer matches your system requirements before ordering.

  • Your inverter is a Growatt off-grid model compatible with ATS 5000T-ES
  • Combined L1-N and L2-N loads do not exceed 5000VA simultaneously
  • L1 to L2 load imbalance stays within 2500W at all times

“Was running my cabin on 120V only and couldn't get the well pump going. Added this transformer to my Growatt SPF and had 240V split phase the same afternoon. Load balancing took some planning but the specs on the page were accurate — my L1/L2 split is within the 2500W window and everything runs clean.”

Frequently Asked Questions

Consider the alternative: running mismatched components that fry your inverter or leave your 240V appliances without power. The ATS 5000T-ES is purpose-built for Growatt off-grid inverters, eliminating the risk of incompatible voltage conversion. One failed appliance — a ruined well pump or compressor — costs far more than this transformer. Think of it as insurance for your entire power system, not an add-on.
This transformer is engineered specifically for Growatt off-grid inverter systems. Using it with a non-Growatt inverter introduces voltage and protocol mismatch risks that can damage both components. If you are running a different inverter brand, contact us for a free system design consultation — we will specify the correct transformer for your exact setup. Compatibility is non-negotiable.
If you need to run any 240V loads — well pumps, HVAC compressors, electric dryers, or split-phase panel distribution — then yes. A 120V-only inverter cannot deliver the voltage these appliances require. The ATS 5000T-ES converts your Growatt inverter output into proper 240V split phase, giving you full access to standard US household circuits from your off-grid battery bank.
Exceeding the 2500W imbalance between L1 and L2 — for example, running 1000W on one leg and 4500W on the other — will cause the transformer to shut down or sustain damage. If your load analysis shows an imbalance greater than 2500W, you need two ATS 5000T-ES units. We include these specifications upfront precisely so you can plan correctly before purchasing.
Yes. The ATS 5000T-ES integrates into an existing Growatt off-grid inverter setup without requiring a full system redesign. If you started with 120V-only output and now need 240V capability, this transformer is the upgrade path. However, confirm your inverter model supports split phase output before purchasing — our free system design consultation can verify compatibility with your specific configuration.
The Growatt ATS 5000T-ES is covered under Growatt's standard manufacturer warranty. As an authorized dealer, Off Grid Vault handles warranty claims directly — you work with us, not a ticket queue. If the transformer does not perform as specified within our 30-day performance guarantee window, we make it right. For installed systems, long-term warranty claims are processed through our support team.
