Battery Catalog

Positioning

The cheapest entry point in the Top Tier lineup and the standard battery for any customer whose existing solar runs on a SolarEdge string inverter. DC-coupled — the battery shares the customer's existing SolarEdge inverter rather than carrying its own, which keeps install cost down and round-trip efficiency up.

Who it's for

SolarEdge-inverter homes where the customer wants the most cost-effective path into a battery — bill-leak capture (GA), self-consumption, or a basic backup tier. Reps lead with this for any SolarEdge customer unless the customer specifically wants modular expansion (then the Nexis) or higher continuous output (then a specialty option).

Coupling and install

DC-coupled retrofit. Pairs with the customer's existing SolarEdge inverter only — does not work with Enphase or non-SolarEdge inverters; don't force-fit. Standard retrofit profile for SolarEdge homes; the crew knows this install well.

Config availability

Offered in both self-consumption ($17,000 cash / $210/mo financed) and backup-capable ($18,500 cash / $228/mo financed) configurations. Self-consumption is the GA default; backup-capable is the default in every other market.

Strengths and trade-offs

Strengths: lowest entry price in the catalog, mature DC-coupled integration, well-understood install. Trade-offs: 5 kW continuous output is the lowest in the lineup — backup loads are essentials only (lights, refrigerator, fans, modem, phones), not whole-home. 10-year manufacturer warranty (70% capacity retention at year 10, unlimited cycles) — shorter than Enphase or Franklin. Don't tell a customer this gets them whole-home backup; don't claim parity with Enphase on continuous power.

Positioning

The standard battery for Enphase-microinverter homes. AC-coupled stack of two IQ Battery 5P units, with the industry's strongest manufacturer warranty.

Who it's for

Enphase-microinverter homes. Default pick for any Enphase customer unless they want the premium specialty backup options (Tesla, Franklin). Strong fit for customers who want more backup headroom than the SolarEdge Home Battery's 5 kW continuous can deliver.

Coupling and install

AC-coupled via the existing Enphase microinverter architecture. Designed for Enphase systems; don't force it onto a SolarEdge home. AC-coupled retrofit fits cleanly behind a microinverter-driven system.

Config availability

Offered in both self-consumption ($17,000 cash / $222/mo financed) and backup-capable ($18,500 cash / $248/mo financed) configurations. Backup-capable is the default in every market except GA.

Strengths and trade-offs

Strengths: 10 kW continuous output — double the SolarEdge Home Battery — supports more simultaneous backup loads (AC compressor start, well pump, more circuits). 15-year manufacturer warranty (each unit: 60% capacity retention at year 15, 6,000 cycles or 26.25 MWh throughput) is the longest in the catalog alongside Franklin. Trade-offs: only fits Enphase-inverter homes; modestly more expensive than the SolarEdge entry on the monthly. The "modular" framing is real but limited — adding capacity means another full IQ 5P pair, not a small incremental block.

Positioning

A modular SolarEdge battery the customer can expand block by block over time. The 10 kWh SKU in the catalog is a 2-block stack; the architecture supports additional blocks later without replacing the unit.

Who it's for

SolarEdge-inverter customers who want the option to grow their storage over time, or who are pure self-consumption with no immediate backup need. A natural pick for SolarEdge homes that need more backup headroom than the standard Home Battery's 5 kW but aren't shopping the specialty Tesla / Franklin tier.

Coupling and install

DC-coupled, like the SolarEdge Home Battery — pairs with the customer's existing SolarEdge inverter only. The modular block stack is the install differentiator; otherwise a similar retrofit profile to the Home Battery.

Config availability

Self-consumption only today ($18,000 cash / $222/mo financed). Backup-capable is pending crew training; once training lands the flag flips and the same Nexis hardware quotes for backup. Don't quote the Nexis as a backup-capable option in the meantime — point the customer at the SolarEdge Home Battery if they want SolarEdge + backup today.

Strengths and trade-offs

Strengths: 7 kW continuous — better backup headroom than the Home Battery's 5 kW when backup support arrives. Modular block-by-block expansion is the standout feature; no other battery in the catalog grows that way. Trade-offs: 10-year manufacturer warranty (matches the Home Battery, shorter than Enphase / Franklin's 15-year); SolarEdge-only inverter compatibility; backup config not yet available, so today it's an incomplete pick for backup-driven customers.

Positioning

The premium specialty backup with a built-in inverter — the only battery in the catalog that doesn't require a separate gateway. Built for customers who want whole-home backup and the highest continuous output the lineup offers.

Who it's for

Customers who explicitly want backup, prioritize continuous output, or have an existing solar system whose inverter brand isn't well-served by the standard SolarEdge / Enphase pair. Also the natural answer for customers who run heavy simultaneous loads during outages (multiple AC circuits, well pump, EV charging).

Coupling and install

AC-coupled retrofit. Connects onto an existing solar system on the AC side regardless of the existing inverter brand — third-party inverters supported, no Tesla solar inverter required. Important sizing nuance: AC-coupled onto an existing system, each Powerwall 3 supports roughly 7.68 kW of existing AC inverter output. Beyond that ratio a second Powerwall is needed or solar production gets throttled. Franklin has no equivalent per-unit ratio, so for very large solar arrays the Franklin can be the cleaner one-unit option.

Config availability

Backup-capable only ($23,000 cash / $284/mo financed). Self-consumption-only is not offered for the Powerwall 3 — the whole product is positioned around backup.

Strengths and trade-offs

Strengths: 11.5 kW continuous output (highest in the catalog), 13.5 kWh capacity, integrated inverter simplifies the install profile, AC-coupling means no inverter swap required. Trade-offs: 10-year manufacturer warranty (shorter than the 15-year on Enphase / Franklin) — matches the SolarEdge tier on duration, not the Enphase / Franklin tier. Largest cash price in the lineup alongside Franklin. The 7.68 kW per-unit AC inverter ratio is a real constraint reps should confirm against the customer's solar size before quoting one unit. Don't sell the Powerwall 3 as the "best" battery — it's the right answer for backup-prioritized customers, not for cost-prioritized ones.

Positioning

The largest-capacity battery in the catalog and the answer for customers who want maximum days of backup. AC-coupled and inverter-agnostic, making it the cleanest fit for unusual existing-system configurations.

Who it's for

Customers who want the most usable capacity (15 kWh — 1.5 kWh more than the Powerwall 3), expect long-duration outages, or have an existing solar system that doesn't pair cleanly with the SolarEdge or Enphase standard batteries. Strong fit for medical-need households, work-from-home customers, and any market with documented multi-day outage history.

Coupling and install

AC-coupled retrofit. Works with any existing inverter brand — no inverter swap required. No per-unit AC sizing ratio like the Powerwall 3, so one Franklin can match an existing solar array of any reasonable residential size.

Config availability

Backup-capable only ($23,000 cash / $284/mo financed). Self-consumption-only is not offered for the Franklin — the product is positioned around backup.

Strengths and trade-offs

Strengths: largest capacity at 15 kWh; 15-year manufacturer warranty (70% capacity retention at year 15, 60 MWh throughput) ties Enphase for longest in the catalog; no AC-coupled sizing ratio, so it's the clean one-unit option for larger solar arrays where the Powerwall 3 might need a second unit. Trade-offs: 10 kW continuous output — lower than the Powerwall 3's 11.5 kW, so for extreme simultaneous-load backup the Powerwall edges it. Largest cash price alongside Tesla. Don't sell the Franklin as "the best battery" — it's the right answer for capacity-prioritized customers, not for output-prioritized ones.
