Frequently Asked Questions
- Yes, the Crown 5.12kWh wall-mounted battery uses standard RS485 and CAN communication protocols, making it compatible with most major 48V hybrid inverters in Pakistan including SAJ H2 series, GoodWe ES Uniq series, Inverex Nitrox series and most other inverters that support standard battery communication. It is not limited to Crown inverters only. For specific compatibility confirmation with your inverter model, contact MartOnline on WhatsApp (+92 324 3493060) before purchase.
- The Crown 5.12kWh wall-mounted battery provides 5.12kWh of usable energy at 95% depth of discharge. For a typical Pakistani home with fans (200W), LED lights (50W), LED TV (100W) and router (20W) — total load 370W — it provides approximately 13.8 hours of backup. Adding a 1 ton inverter AC (900W) brings total load to 1270W, reducing backup time to approximately 4 hours. For 6-8 hours of backup including AC, 2-3 units in parallel (10.24-15.36kWh) are recommended. Multiple Crown 5.12kWh units can be stacked and paralleled to increase total storage capacity.
- The Crown 5.12kWh wall battery and Luminey Atrix 5kWh are both 5kWh LFP rack/wall batteries competing in the same segment. Capacity: both 5.12kWh, nearly identical. DOD: Crown at 95% versus Luminey at 100% — Luminey slightly better. Cycle life: both 6000+. Design life: both 15 years. Installation: Crown is wall-mounted while Luminey Atrix is rack-mounted — Crown saves floor space. Price: Crown at Rs 250,000 versus Luminey at Rs 230,000 — Luminey slightly cheaper. IP rating: Crown at IP30 (dustproof) versus Luminey at IP21. Brand: Crown Micro is a local Pakistani brand with strong local support; Luminey is a local brand using Sunwoda cells. Both are good choices — Crown if wall-mounting is preferred, Luminey if cost is priority.
- The Crown 5.12kWh wall-mounted battery has a 15-year design life at 25°C and 6000+ charge cycles — at one cycle per day, this equals over 16 years of daily use. The battery comes with a 5-year manufacturer warranty from Crown Micro Global. Crown local service network ensures warranty claims are resolved domestically without international shipping. For a residential solar installation expected to run for 20-25 years alongside solar panels, the 15-year design life ensures the battery remains functional for the majority of the system lifetime without replacement.
- Multiple Crown 5.12kWh wall-mounted batteries can be connected in parallel to increase total storage capacity. The technical maximum is determined by your inverter capability, but most hybrid inverters support 4-8 batteries in parallel. For a 16kWh total storage (full overnight backup for a medium Pakistani home), 3 units of Crown 5.12kWh batteries in parallel are needed. For 20kWh+ storage for a large home with multiple ACs, 4 units are recommended. Contact MartOnline for parallel configuration guidance specific to your inverter and home size.
