The Long-Life Lithium Battery That Talks to Almost Any Inverter

You've got a perfectly good solar setup already humming on the roof. The inverter is doing its job. But when the sun goes down, you're still pulling from the grid, and when an outage hits, the whole system goes dark. Adding battery storage is the obvious next step—except every time you look, it feels like you're being pushed into a single-brand ecosystem with proprietary communications and a price tag that's hard to swallow. The FBP Series is the battery module that breaks that cycle. It's a residential lithium battery built to slot into your existing solar system, talk to whatever inverter you already have, and keep working for so long you'll probably forget when you installed it.

The Chemistry That Makes 8,000 Cycles Possible

Inside the FBP is lithium iron phosphate—LiFePO4, for short. That's the same chemistry used in electric buses and grid-scale storage, chosen for one reason above all: it lasts. The FBP is rated for 8,000 charge-discharge cycles at standard depth. If you cycle the battery fully once a day—charge during sunlight, discharge overnight—that's more than 20 years of operation before the cells degrade to 80% of their original capacity. Realistically, you won't cycle it that hard every single day. You might only use half the capacity before the sun comes back up, which stretches the lifespan even further. Compare that to a lead-acid bank that needs replacement after 500 to 800 cycles, or even early lithium packs that start fading after 2,000 or 3,000. The FBP is built for the long haul, and the 10-year design life is a conservative estimate, not an optimistic guess.

Two Voltages, Wide Compatibility

The FBP comes in two nominal voltages: 25.6V (designed for 24V systems) and 51.2V (designed for 48V systems). That covers the vast majority of residential solar inverters, off-grid inverters, and hybrid systems on the market. Whether you're building a new cabin from scratch or adding storage to an existing grid-tied solar setup, there's a voltage that matches. And because the module has a high continuous discharge rate, it can handle the startup surge of a well pump, an air conditioner, or a full kitchen during an outage without the voltage sagging.

Communication That Doesn't Lock You In

This is where the FBP truly separates itself from the pack. Many lithium battery brands force you into their own inverter ecosystem by using a closed communication protocol. That's great for their sales team, but terrible for your flexibility. The FBP comes with a full suite of open communication interfaces: RS232, RS485, CAN, WiFi, Bluetooth, and dry contacts. That means it can talk to inverters and charge controllers from most major manufacturers right out of the box. No proprietary gateway boxes, no adaptor dongles, no hoping for a firmware update that may never come. If your inverter supports standard lithium battery communication over CAN or RS485, the FBP will almost certainly work with it. That kind of open-ecosystem thinking makes the FBP the battery of choice for installers who work with multiple inverter brands and for homeowners who don't want to be married to a single manufacturer's product line.

A BMS That Goes Beyond the Basics

Every lithium battery has a Battery Management System. The FBP's is notably thorough. Beyond the standard protections—over-charge, over-discharge, over-current, short circuit, and temperature extremes—it provides continuous state-of-charge (SOC) and state-of-health (SOH) monitoring, so you always know exactly how much energy is left and how healthy the pack is. There's even an anti-theft function that can disable the battery if it's disconnected without authorization, a feature that matters a lot in remote installations or ground-mounted solar farms where equipment sometimes walks away.

The BMS also handles cell balancing actively, not passively. That means it doesn't just bleed off excess voltage from the highest cells as waste heat; it redistributes energy to keep all cells at the same voltage, which improves both safety and usable capacity. Over time, this active balancing pays off in longer runtime and fewer surprises.

A Front Display That Tells You What's Going On

You don't need to fire up an app or walk to the inverter just to check the battery. The FBP has a front-panel display that shows you the essentials: state of charge as a percentage, voltage, current, and any active alarms. One glance tells you whether the battery is charging, discharging, or standing by. In a dim garage, that's a lot more practical than hunting for your phone. And when the system is communicating with the inverter over CAN or RS485, the display on the battery and the display on the inverter will agree—no confusion, no mismatched data.

Quiet, Cool, and Good-Looking Enough to Live Inside

The FBP doesn't look like a piece of industrial equipment. Its enclosure is clean, modern, and compact—something you wouldn't mind having in a utility room, a hallway, or even a finished garage. It's passively cooled under normal loads, so there's no fan noise. When the discharge rate climbs, the internal thermal management keeps temperatures in check without the constant hum that some competing packs produce. And because it's sealed and rated for indoor installation, you don't need to build a special ventilated enclosure.

Who the FBP Is For

This battery is designed squarely for residential storage—homeowners who already have solar and want to add storage, or those building a new off-grid or hybrid system and looking for a reliable lithium pack that won't need replacing every few years. It's also a solid pick for installers who want a battery they can confidently pair with multiple inverter brands without compatibility headaches. Common deployments:

`Adding storage to an existing grid-tied solar system to capture daytime surplus

`Powering essential loads through nighttime and blackouts

`Building a new off-grid cabin or tiny home with a 24V or 48V solar setup

`Replacing an aging lead-acid bank with a drop-in lithium upgrade

`Pairing with a generator to create a seamless backup power system

If you've been waiting for a battery that checks all the boxes—long life, open communication, solid BMS, and a design that doesn't look out of place in a modern home—the FBP Series is the module that finishes your solar setup the right way. No lock-in. No compromises. Just clean, quiet, durable storage that's ready to work with the equipment you already trust.
