Reading the specifications

SunMaxx Battery Charger 20A is listed with 3 published specifications from SunMaxx, including battery charging voltage of DC 12V, charge current of 20A and input voltage of 230V AC. 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.

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.

Common mistakes

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.
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.

Price and availability in Pakistan

SunMaxx Battery Charger 20A is listed at ₨ 2,500 (PKR) for Pakistan. 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 Pakistan: warranty cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports SunMaxx locally before ordering.

SunMaxx Battery Charger 20A — frequently asked questions

How much does SunMaxx Battery Charger 20A cost?

SunMaxx Battery Charger 20A is listed at ₨ 2,500 (PKR) for Pakistan. 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.

What are the specifications of SunMaxx Battery Charger 20A?

We hold 3 published specifications for this battery, including battery charging voltage DC 12V, charge current 20A and input voltage 230V AC. The full table is on this page, listed under model SUNX-05.

Who makes SunMaxx Battery Charger 20A?

SunMaxx Battery Charger 20A is a SunMaxx product, listed under batteries with model reference SUNX-05. The SunMaxx brand page lists the rest of its range so you can compare across the catalogue.

Is SunMaxx Battery Charger 20A 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. 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.

Where can I buy SunMaxx Battery Charger 20A in Pakistan?

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