Frequently Asked Questions What types of Batteries / Energy Storage Systems (ESS) do you offer for energy storage?We supply a variety of batteries, including lithium-ion, AGM, and gel deep-cycle batteries. Each type suits different applications and budgets. How do I choose the right battery capacity for my solar system?Estimate your daily energy usage, account for backup needs, and factor in days of autonomy. Use these numbers to select a battery bank with the appropriate capacity (in kWh). Can your energy storage batteries be paired with any inverter?Many of our batteries are compatible with common inverters, but you must check for voltage, current limits, and chemistry. We can help you match batteries with inverters. What is the expected lifespan of your energy storage batteries?Lifespan depends on type and usage. Lithium-ion batteries typically last for 5,000+ cycles, while AGM or gel batteries often provide several hundred to a few thousand cycles. Are your batteries safe and reliable?Yes. We stock batteries from trusted manufacturers. Our batteries include built-in protections like overcharge, over-discharge, and thermal management. How do I maintain my energy storage batteries?For best performance: keep batteries in a cool, dry area; avoid extreme temperature swings; perform regular state-of-charge checks; and follow manufacturer guidelines for float charging. Do you offer warranty or support for your battery systems?Yes. Our batteries come with manufacturer warranties. Additionally, our technical team helps with installation support, system sizing, and troubleshooting. { "@context": "https://schema.org", "@type": "FAQPage", "mainEntity": [{ "@type": "Question", "name": "What types of batteries do you offer for energy storage?", "acceptedAnswer": { "@type": "Answer", "text": "We supply a variety of batteries, including lithium-ion, AGM, and gel deep-cycle batteries.
