What these specifications mean

Detailed specifications for EG4 LifePower4 V2 Lithium Battery | 48V 100Ah | 5.12kWh Server Rack | UL1973, UL9540A | Auto-Addressing | 10-Year Warranty have not been published yet. EG4 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 round-trip efficiency, around 90–95% for lithium and 75–85% for lead-acid, communication protocol (CAN or RS485) for talking to the inverter, nominal capacity in ampere-hours (Ah) or kilowatt-hours (kWh) and usable capacity after depth of discharge — LiFePO4 typically allows 80–100%, lead-acid closer to 50%. 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.

Common mistakes

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 Arab Emirates

EG4 LifePower4 V2 Lithium Battery | 48V 100Ah | 5.12kWh Server Rack | UL1973, UL9540A | Auto-Addressing | 10-Year Warranty is listed at $ 1,471 (USD) for United Arab Emirates. 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 Arab Emirates: warranty cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports EG4 locally before ordering.

EG4 LifePower4 V2 Lithium Battery | 48V 100Ah | 5.12kWh Server Rack | UL1973, UL9540A | Auto-Addressing | 10-Year Warranty — frequently asked questions

EG4 LifePower4 V2 Lithium Battery | 48V 100Ah | 5.12kWh Server Rack | UL1973, UL9540A | Auto-Addressing | 10-Year Warranty is listed at $ 1,471 (USD) for United Arab Emirates. 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.

EG4 LifePower4 V2 Lithium Battery | 48V 100Ah | 5.12kWh Server Rack | UL1973, UL9540A | Auto-Addressing | 10-Year Warranty is a EG4 product, listed under batteries with model reference 1511105. The EG4 brand page lists the rest of its range so you can compare across the catalogue.

That depends on what it has to connect to. For a battery, check communication protocol (CAN or RS485) for talking to the inverter, nominal capacity in ampere-hours (Ah) or kilowatt-hours (kWh) and usable capacity after depth of discharge — LiFePO4 typically allows 80–100%, lead-acid closer to 50% against the rest of your equipment before price enters the decision. 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.

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