Reading the specifications

Detailed specifications for Epoch 12V 120Ah - Group 27 - Cranking & Deep Cycle Lithium Battery (Dual Purpose) have not been published yet. Epoch lists this battery in the Batteries, and we add fields as the manufacturer releases them — in the meantime, ask your distributor for the datasheet before ordering.

For a battery, the figures that matter most are cycle life at a stated depth of discharge, commonly 3,000–6,000 cycles for LiFePO4, round-trip efficiency, around 90–95% for lithium and 75–85% for lead-acid, communication protocol (CAN or RS485) for talking to the inverter and nominal capacity in ampere-hours (Ah) or kilowatt-hours (kWh). Storage is what turns a solar array from a daytime bill-reducer into a system that covers evening loads and rides through outages. It is normally the single most expensive component, so sizing it correctly matters more than with any other part.

Before you buy a battery

The checks below apply to any battery. Run them against the specification table above — most disappointing solar purchases are compatible-on-paper units that fail one of these in practice.

Match voltage to the inverter, and confirm the battery appears on the inverter maker's supported list. Closed-loop communication lets the inverter respect the battery's real charge limits instead of guessing.
Read the warranty in full: lithium warranties are stated as a term plus either a cycle count or a total energy throughput, and whichever limit arrives first ends the cover.
Leave room to expand. Packs that parallel cleanly let you add capacity later; ones that do not force a full replacement.
Compare usable kilowatt-hours, not nameplate capacity. A 100 Ah lead-acid battery at 12 V is nominally 1.2 kWh but only about 0.6 kWh is safely usable, while a 100 Ah LiFePO4 pack gives you roughly 1.0–1.2 kWh.

What people get wrong

Installing lithium packs in an unventilated, hot enclosure. Sustained high temperature is the fastest way to lose cycle life.
Ignoring the charge current limit and pairing a large array with a small bank, which trips protection and shortens life.
Mixing old and new batteries, or different chemistries, in one bank. The weakest unit drags the whole bank down and can be damaged by the others.

Price and availability in United States

Epoch 12V 120Ah - Group 27 - Cranking & Deep Cycle Lithium Battery (Dual Purpose) is listed at $ 799 (USD) for United States. Solar pricing moves with supply, import duties and exchange rates, and distributors set their own margins, so treat this as a comparison reference and confirm the current figure before you order.

SolarBazaar compares equipment rather than selling it. Shortlist here on specification and price, then buy from an authorised distributor or installer in United States: warranty cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports Epoch locally before ordering.

Epoch 12V 120Ah - Group 27 - Cranking & Deep Cycle Lithium Battery (Dual Purpose) — frequently asked questions

How much does Epoch 12V 120Ah - Group 27 - Cranking & Deep Cycle Lithium Battery (Dual Purpose) cost?

Epoch 12V 120Ah - Group 27 - Cranking & Deep Cycle Lithium Battery (Dual Purpose) is listed at $ 799 (USD) for United States. The figure is indicative — solar prices move with supply, duties and exchange rates, and each distributor sets its own margin — so confirm the current price with a supplier before ordering.

Who makes Epoch 12V 120Ah - Group 27 - Cranking & Deep Cycle Lithium Battery (Dual Purpose)?

Epoch 12V 120Ah - Group 27 - Cranking & Deep Cycle Lithium Battery (Dual Purpose) is a Epoch product, listed under batteries with model reference DP12120H. The Epoch brand page lists the rest of its range so you can compare across the catalogue.

Is Epoch 12V 120Ah - Group 27 - Cranking & Deep Cycle Lithium Battery (Dual Purpose) right for my system?

That depends on what it has to connect to. For a battery, check system voltage: 12 V, 24 V and 48 V for low-voltage packs, or a high-voltage stack, continuous charge and discharge current, which limits how much power you can draw from the pack and cycle life at a stated depth of discharge, commonly 3,000–6,000 cycles for LiFePO4 against the rest of your equipment before price enters the decision. Read the warranty in full: lithium warranties are stated as a term plus either a cycle count or a total energy throughput, and whichever limit arrives first ends the cover.

Where can I buy Epoch 12V 120Ah - Group 27 - Cranking & Deep Cycle Lithium Battery (Dual Purpose) in United States?

SolarBazaar lists and compares equipment rather than selling it. Use the specifications and price here to shortlist, then buy through an authorised distributor or installer in United States — buying in-channel is what keeps the manufacturer's warranty valid.
