Tigo Energy · TSI-11.4K-US + TSB-10-US + 200 A ATS
Ready to buy
The retained reference is $7,079.62 current documented equipment-package reference. Require exact part numbers, one-line, load schedule, listing set, permit and utility scope, commissioning tests, credentials, warranty and final installed price before signing.
Current market
Each line carries its own check date because price, software, specifications, and product cycle do not age at the same speed.
Use as a component boundary rather than an order promise; confirm stock, current distributor, cables, solar, service and panel work, generator limitation, freight, tax, engineering, permit, utility and installation
Tigo EI is defended as a clearly bounded inverter, battery and ATS package, but the current availability flag and missing generator path make distributor and service verification mandatory.
Other paths
These are not generic competitors. Each one represents a different way to buy into the same market.

What changed
Older observations stay in the ledger when the current view changes. That lets a buyer tell the difference between an old complaint, an active issue, and a problem that was corrected.
EI Residential Solution was checked against current manufacturer identity, specification or manual, support and privacy, current U.S. price or documented package boundary, independent review and bounded owner or installer evidence.
Each amount stays tied to its source and capture date. Conflicting prices remain visible until the seller resolves them.

Owner experience
Owner and installer evidence is retained as a quote, commissioning, outage-test, software and service checklist for EI Residential Solution, not an accuracy, safety, runtime, savings or reliability rate.
Reports are self-selected and span different capacities, loads, solar, generators, services, panels, utilities, codes, climates, installers, firmware, tariffs and system ages. They cannot prove code compliance, fire safety, savings, runtime, resilience, warranty performance or whole-home outcomes for another site.Self-selected exact-system owners and installers discuss quotations, commissioning, outage tests, standby loss, firmware, app access, service and repair. Reports are anecdotal, configuration-specific and do not establish runtime, savings, safety, reliability or a population failure rate.
Confirm stock and warranty acceptance in writing, then require the exact TSI, TSB and ATS numbers on the permit and commissioning record

The page separates what a source states directly from what we conclude across sources.
Tigo Energy identifies the current TSI-11.4K-US + TSB-10-US + 200 A ATS system as a U.S.-only package combining an 11.4 kW hybrid inverter, 9.9 kWh total or 9.0 kWh usable LFP battery and required 200 A automatic transfer switch.
The current listing records $7,079.62 for one TSB-10-US, TSI-11.4K-US and 200 A ATS package, but marks the variant unavailable.
Current technical documents support the retained capacity, power or disclosed peak gap, coupling, controls, transfer, expansion, ambient, safety, listing and installation boundaries.
Confirm current battery, inverter and ATS warranties separately, including cycle, capacity, registration, internet, authorized-installer, removal, freight and transfer terms. Document an alternate distributor before buying unavailable stock

DOE guidance treats battery storage as a designed and permitted electrical system involving listing, siting, overcurrent, disconnect, signage, rapid shutdown, commissioning, utility and AHJ checks rather than a plug-in appliance.
Current IRS guidance says the section 25D residential credit applied through December 31, 2025 and is unavailable for property placed in service after that date; other ownership and incentive routes require separate advice.
Current marketplace guidance places a typical installed home battery near $15,000 before local incentives and emphasizes multiple complete quotes, permits and installer scope rather than equipment price alone.
An independent product analysis reviews Tigo's integrated architecture, usable energy, power, efficiency and installer-led positioning. It is specification-led rather than a population reliability study.
Self-selected exact-system owners and installers discuss quotations, commissioning, outage tests, standby loss, firmware, app access, service and repair. Reports are anecdotal, configuration-specific and do not establish runtime, savings, safety, reliability or a population failure rate.
EP Cube 2.0 20 kWh is the modular second-generation solar and smart-load system alternative at $13,493 current 20 kWh equipment price.
Avalon High Voltage ESS is the integrated smart-load high-voltage system alternative at $17,950 current approximate 19.6 kWh equipment reference.
Manufacturer identity, specification or manual, support, current U.S. price or a documented complete-system boundary, independent editorial and bounded owner or installer evidence were checked on August 19, 2026. This market covers current U.S.-supported stationary residential battery and energy-storage systems or materially different complete configurations. It excludes portable power stations, EV-only vehicle-to-home systems, bare cells and rack batteries without a supported residential system path, unsupported marketplace equipment, discontinued or orphaned systems, cosmetic bundles and capacity-module padding. Preserve exact nameplate and usable energy, continuous power, timed peak or its disclosed absence, AC or DC coupling, inverter, controller, gateway, transfer and islanding, backed-up circuits versus service, generator and solar compatibility, expansion, ambient derating, mounting, thermal management, fire and stored-energy hazards, and any coolant, refrigerant or suppression-service requirement. LFP or another chemistry, BMS protections, UL 9540 system listing, UL 9540A test evidence and UL 1973 battery listing reduce or characterize specific risks but do not make a system fire-free or guarantee AHJ approval. Retain the exact listed combination, NEC edition, permit, fire review, utility interconnection and permission to operate. Preserve installer access, app, local control, cloud, privacy, firmware, warranty, throughput, parts and service. Current IRS guidance says section 25D is unavailable for residential property placed in service after December 31, 2025; state, utility, lease, business and VPP programs are separate. No capacity, power, transfer speed, solar, generator, weather mode, tariff schedule, app forecast, quote or incentive guarantees runtime, savings, outage survival, resilience or operation of every home load.
