What these specifications mean

Ever Best 5.1kWh IP20 Lithium Battery 51V 100ah is listed with 9 published specifications from Ever Best, including efficiency of ~98% round-trip efficiency, discharge current of 200A (varies by brand), nominal voltage of 51.2V and battery chemistry of LiFePO₄ (Lithium Iron Phosphate). 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 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.

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.
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.

Common mistakes

Sizing the bank for total daily consumption rather than after-dark consumption, which typically doubles the cost for no benefit.
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.

Price and availability

Ever Best 5.1kWh IP20 Lithium Battery 51V 100ah is listed at ₨ 242,000 (PKR). 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 your country: warranty cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports Ever Best locally before ordering.

What are the specifications of Ever Best 5.1kWh IP20 Lithium Battery 51V 100ah?

We hold 9 published specifications for this battery, including efficiency ~98% round-trip efficiency, discharge current 200A (varies by brand), nominal voltage 51.2V, battery chemistry LiFePO₄ (Lithium Iron Phosphate) and capacity 100Ah. The full table is on this page, listed under model WYTH-72.

Who makes Ever Best 5.1kWh IP20 Lithium Battery 51V 100ah?

Ever Best 5.1kWh IP20 Lithium Battery 51V 100ah is a Ever Best product, listed under batteries with model reference WYTH-72. The Ever Best brand page lists the rest of its range so you can compare across the catalogue.

Is Ever Best 5.1kWh IP20 Lithium Battery 51V 100ah right for my system?

That depends on what it has to connect to. For a battery, check continuous charge and discharge current, which limits how much power you can draw from the pack, cycle life at a stated depth of discharge, commonly 3,000–6,000 cycles for LiFePO4 and round-trip efficiency, around 90–95% for lithium and 75–85% for lead-acid against the rest of your equipment before price enters the decision. 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.

Where can I buy Ever Best 5.1kWh IP20 Lithium Battery 51V 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.
