What these specifications mean

Epever 5kWh Wall Mounted Lithium Battery 51.2V 100Ah is listed with 12 published specifications from Epever, including display of LCD, WiFi, discharge current of 50 A, discharge temperature of Charge: 0°C~+55°C / Discharge: -20°C~+60°C and nominal voltage of 51.2. Those figures are what decide whether this unit fits your system, so read them against the equipment it will connect to before comparing price.

For a battery, the figures that matter most are usable capacity after depth of discharge — LiFePO4 typically allows 80–100%, lead-acid closer to 50%, 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. 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.

Choosing a battery: the checks that matter

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.

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.
Size from your evening consumption. Add up what actually runs after sunset for the hours you want covered, then divide by the usable capacity per unit — that number, not the array size, sets how many batteries you need.
Check the continuous discharge rating against your inverter. A battery that stores plenty of energy but can only deliver 50 A cannot support a large inverter at full output.

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

No price is published for Epever 5kWh Wall Mounted Lithium Battery 51.2V 100Ah at the moment. Pricing on solar equipment moves with supply and exchange rates, and some distributors quote only on request — the specifications above are still directly comparable against alternatives that do list a price.

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

Epever 5kWh Wall Mounted Lithium Battery 51.2V 100Ah — frequently asked questions

What are the specifications of Epever 5kWh Wall Mounted Lithium Battery 51.2V 100Ah?

We hold 12 published specifications for this battery, including display LCD, WiFi, discharge current 50 A, discharge temperature Charge: 0°C~+55°C / Discharge: -20°C~+60°C, nominal voltage 51.2 and battery type LiFePO4. The full table is on this page, listed under model EPER-04.

Who makes Epever 5kWh Wall Mounted Lithium Battery 51.2V 100Ah?

Epever 5kWh Wall Mounted Lithium Battery 51.2V 100Ah is a Epever product, listed under batteries with model reference EPER-04. The Epever brand page lists the rest of its range so you can compare across the catalogue.

Is Epever 5kWh Wall Mounted Lithium Battery 51.2V 100Ah right for my system?

That depends on what it has to connect to. For a battery, check nominal capacity in ampere-hours (Ah) or kilowatt-hours (kWh), usable capacity after depth of discharge — LiFePO4 typically allows 80–100%, lead-acid closer to 50% and system voltage: 12 V, 24 V and 48 V for low-voltage packs, or a high-voltage stack 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 Epever 5kWh Wall Mounted Lithium Battery 51.2V 100Ah?

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 — buying in-channel is what keeps the manufacturer's warranty valid.
