The TTNergy Roller (TTN-ROLLER21) is a true all in one solar inverter that fuses a 3.6–6.2 kW pure sine wave hybrid inverter and a 5.12 kWh LiFePO4 battery into a single rollable enclosure. Instead of buying, wiring and commissioning an inverter, battery cabinet, BMS and communication kit separately, EPC contractors, distributors and system integrators receive one plug-and-play energy unit — pre-wired, factory-tested, and shipped with CE, UL (CETL/CSA), IEC 62109, RoHS and UN38.3 certifications.
Backed by TTN Electric’s manufacturing since 1994, the Roller supports both grid-tied and off-grid households, small commercial backup, telecom sites, and rural electrification projects across 110 V and 220 V single-phase markets — a genuine 2-in-1 solar inverter and battery solution engineered for global B2B deployment.
Conventional residential solar systems require you to source a hybrid inverter, a low-voltage or high-voltage battery, a battery cabinet, a communication cable, an isolator and several protection breakers from three or four different vendors. Every added SKU is another failure point, another warranty claim, and another day of on-site commissioning.
The Roller all in one solar inverter collapses that BOM into one wall-mounted, wheel-equipped unit:
For distributors, this translates to a higher unit ASP with a shorter sales cycle: one Roller replaces three line items on a quote sheet.
Three power tiers cover most residential and light-commercial loads:
Shared platform specs:
Because the inverter and battery are pre-matched at the factory, buyers avoid the classic mismatch problem — under-sized BMS discharge current, missing battery communication protocol, or wrong DC ripple tolerance.
The Roller ships with four factory work modes that can be selected from the front LCD or the WiFi app:
These modes make the Roller a genuine hybrid all in one solar inverter rather than a passive off-grid box — the same hardware serves both energy-independence and bill-arbitrage use cases.
Every Roller carries a 51.2 V / 100 Ah LiFePO4 (5.12 kWh) pack with the following field-relevant characteristics:
LiFePO4 chemistry is intrinsically safer than NMC — no thermal runaway propagation at typical residential ambient — which is why the Roller carries only an IP21 indoor rating without needing an external fireproof battery cabinet.
Unlike traditional inverters that expose only an AC terminal block, the Roller adds usable DC and USB rails directly on the front panel:
This makes the Roller an all in one solar inverter and a workable solar generator out of the box, opening two distinct sales channels from a single SKU.
Two features matter more than data-sheet numbers to end-users:
Add foldable / portable PV panel compatibility and the Roller becomes the only all in one solar inverter in its class that can be commissioned as a fully mobile emergency-power unit for disaster relief, mining exploration camps, and event power rentals.
An all in one solar inverter combines the hybrid inverter, MPPT solar charge controller, battery, BMS and AC/DC output ports inside a single enclosure. The TTNergy Roller is a 2-in-1 example: one cabinet holds a 3.6–6.2 kW hybrid inverter and a 5.12 kWh LiFePO4 battery, eliminating the need to source and wire separate components.
Yes. The Roller supports full off-grid operation using solar panels and the built-in 5.12 kWh LiFePO4 battery, and it can also run in grid-tied hybrid mode with four selectable work modes (PV priority, battery priority, grid priority, utility charging).
Maximum PV input is 4,200 W (3.6 kW model), 5,500 W (5.5 kW model) or 6,200 W (6.2 kW model), with an MPPT range of 120–450 Vdc and Voc up to 500 Vdc — typically 6–14 panels of 400–550 W each.
The integrated 51.2 V / 100 Ah LiFePO4 battery is rated for more than 6,000 cycles at 80 % Depth of Discharge, equivalent to over 15 years of daily cycling under normal residential use.
The inverter is certified to CE, UL (CETL, CSA), IEC 62109, RoHS and EN61000 EMC. The battery cells meet CE, UL, IEC 62109-1 & -2, IEC 62477, EN61000 and UN38.3. The battery pack additionally holds UN38.3, MSDS and a Transportation Safety Certificate, allowing international sea and air freight.
The Roller is designed for professional installation, but its portable roller wheel design and pre-wired inverter-battery architecture mean that a qualified electrician can typically complete commissioning in 2–3 hours, compared to 1–2 days for a traditional split system.
Yes. AC output is single-phase, selectable at 110 V or 220 V, with 50/60 Hz auto-matching. This makes it deployable in North America, Latin America, Europe, Middle East, Africa and most of Asia-Pacific with the same hardware SKU.
