The SolaX Triple Power 5.8kWh TP58 Master Battery V3 is the starting battery for a compatible high-voltage TP58 system. Sold as the T-BAT H 5.8(H) V3, it combines a 5.8kWh battery module with an integrated battery management system, making it the essential first battery in the stack.

This master battery cannot be replaced by a slave unit and must be used when building a new TP58 battery system. SolaX specifies LiFePO₄ chemistry, 95% depth of discharge, over 6000 cycles, IP66 protection and built-in two-level battery heating, giving it a strong specification for modern residential battery storage.

The TP58 Master V3 can be wall or floor mounted and supports modular expansion with matching TP58 slave batteries. It is also presented as compatible with existing TP58 V2 systems, which can be useful for certain replacement and upgrade projects.

Why we recommend it: it is the correct battery to start a SolaX TP58 system, offers strong usable capacity and modern protection features, and gives a clear path for future expansion within the same battery family.

The SolaX Triple Power 5.8kWh TP58 Slave Battery V3 is the expansion battery for a compatible TP58 high-voltage storage system. Sold as HV11550(H) V3, it adds a further 5.8kWh battery module to a setup that already has a TP58 Master battery in place.

This battery cannot operate on its own, so it should only be used where a matching master battery is already installed or being ordered alongside it. SolaX product information highlights LiFePO₄ chemistry, 95% depth of discharge, over 6000 cycles, IP66 protection and built-in battery heating.

It is a strong option for customers who want to increase storage within the same SolaX battery family without replacing the whole system. Channel guidance also presents TP58 V3 batteries as compatible with TP58 master batteries in both V2 and V3 form.

Why we recommend it: it is a simple and effective way to add more storage to a compatible TP58 system while keeping the same battery platform, same form factor and a clear upgrade path.
