What these specifications mean
SIMTEK 24V 20A Battery Charger & Status Indicator is listed with 18 published specifications from SIMTEK, including display of L.E.D Display, ambient temperature of - 0 C to + 55 C, over temperature protection of Out Put Shutdown and parallel operation of Yes. 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 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%, system voltage: 12 V, 24 V and 48 V for low-voltage packs, or a high-voltage stack and continuous charge and discharge current, which limits how much power you can draw from the pack. 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.
What to check before ordering
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.
- 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.
- 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 buyers lose money
- 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
SIMTEK 24V 20A Battery Charger & Status Indicator is listed at ₨ 12,800 (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 SIMTEK locally before ordering.
SIMTEK 24V 20A Battery Charger & Status Indicator — frequently asked questions
How much does SIMTEK 24V 20A Battery Charger & Status Indicator cost?
SIMTEK 24V 20A Battery Charger & Status Indicator is listed at ₨ 12,800 (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 SIMTEK 24V 20A Battery Charger & Status Indicator?
We hold 18 published specifications for this battery, including display L.E.D Display, ambient temperature - 0 C to + 55 C, over temperature protection Out Put Shutdown, parallel operation Yes and weight 1.4 Kg. The full table is on this page, listed under model SIMK-21.
Who makes SIMTEK 24V 20A Battery Charger & Status Indicator?
SIMTEK 24V 20A Battery Charger & Status Indicator is a SIMTEK product, listed under batteries with model reference SIMK-21. The SIMTEK brand page lists the rest of its range so you can compare across the catalogue.
Is SIMTEK 24V 20A Battery Charger & Status Indicator right for my system?
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. 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.
Where can I buy SIMTEK 24V 20A Battery Charger & Status Indicator 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.
