About this product

What it is, and what it is for

Growatt MIN 3800TL-XH-US 3.8 kW Grid-Tie Battery-Ready Inverter

A 3.8 kW single-phase grid-tie inverter for a small roof of eight to sixteen 450 W panels, with the battery and backup path built in for later. 98 percent peak efficiency, 97 percent CEC weighted.

The MIN XH-US is Growatt's battery-ready grid-tie inverter for US homes: it works as a plain string inverter on day one, and becomes a backup system when a Growatt APX or ARO high-voltage battery and the XH backup box are added later, without replacing the inverter. It can be DC-coupled (panels and battery on the inverter) or AC-coupled onto an existing solar system, runs self-consumption, zero-export, time-of-use and off-grid modes, and can dark-start from the battery with the grid down. Rapid shutdown and arc-fault protection are built in, it is listed to UL 1741 SA/SB and CA Rule 21 (HECO compliant), and it mounts indoors or out in a NEMA 4X case with no fan. Monitoring is by Wi-Fi and LAN through the Growatt app; 4G is optional.

Sizing: Two MPP trackers with four string inputs, 600 V maximum PV voltage, and a 2.0 DC/AC ratio, so up to 7.6 kW of panels; 16 A maximum output on a 208 or 240 V service. Pairs with an APX 5 kWh to 30 kWh high-voltage battery for partial-home backup.

Which version: choose Partial Home Backup (V2) to back up an essentials sub-panel through the SYN 200-XH-US, or Whole Home Backup (V3) to back up the main panel through the ATS-XH-US transfer switch; the backup box, battery and smart meter are sold separately. The inverter carries Growatt's 10-year warranty, extendable to 15 or 20 years.

Specifications are from Growatt's datasheet and are for reference; the installation must follow the manual, the NEC and local code, be carried out by a licensed electrician, and the interconnection approved by your utility.

Common questions

Before you order.

If yours isn't here, ask an engineer. It costs nothing and it's the step most people skip.

What if I'm not sure this is the right product?

Ask before you order. Send us what you need to run, or your pool or well figures, and an engineer will confirm the choice — it costs nothing. Or use the finder below, which sizes from what you actually run and shows its reasoning.
