MPPT converts surplus voltage into amps; PWM throws it away · review
SOGTICPS 100 A, 12/24/36/48 V, 100 V PV maximum review
A 100 A controller for 12 to 48 V systems with a published 100 V PV input ceiling, whose listing describes it as combining MPPT and PWM charging technology.
The bottom line One of the few controllers here to publish its PV input ceiling, with four named chemistries and seven operating modes. Its description of its own charging technology is internally confused, and it gives no wiring guidance at 100 A.
A 100 A controller with a published input ceiling and a confused description of how it charges.
The number that matters, published
100 V maximum PV input. Seven of the eleven controllers in this catalogue publish no ceiling at all. A string above the ceiling damages the input, open-circuit voltage rises as cells cool, and without the figure the calculation cannot be attempted.
The description that does not resolve
The first bullet states that the controller combines MPPT and PWM charging technology with high efficiency and a tracking efficiency of at least 99.5 %. MPPT and PWM are alternatives, not ingredients. Whether this unit switches between them, or implements one and markets the other, is not established by the page.
What it does well
Four chemistries named — sealed, gel, flooded, LiFePO4 — with automatic voltage detection from 12 to 48 V. Seven operating modes, including light control with a ten-minute delay, which is what a street lighting or garden installation actually uses.
What is absent at 100 A
Wiring sizes. Terminal capacity. Enclosure rating. A hundred amps is a serious current and the listing offers no guidance on the cable that carries it.
Availability
German, French, Italian and Spanish Amazon stores quoted 36 € to 45 € when this page was compiled.
British Amazon store carries it too, priced in its own currency, which the euro range above deliberately omits.
American Amazon store returned nothing at all, so the buy button there runs a search instead of landing on an empty page.

What it gets right, and what it leaves out
Strengths
The maximum PV input voltage is published — 100 V — which four of eleven controllers here manage
Four battery chemistries named, including LiFePO4
Seven operating modes including light control with a delay, for street lighting applications
Compromises
The first bullet says it combines MPPT and PWM technology, which are two different approaches rather than a combination
100 A at 100 V maximum input is an unusual pairing that the listing does not explain
No wiring sizes, on a controller rated at 100 A

Questions owners ask about this one
What does “combines MPPT and PWM” mean?
Those are two different charging approaches: one tracks the panel’s best operating point, the other ties the panel to the battery voltage. A controller can implement either, or switch between them. The phrase as written describes a combination rather than a choice, and this page reports it as the maker’s wording.
Why does 100 A need wiring sizes?
Because 100 A through an undersized cable is a fire, not an inefficiency. A controller rated at that current should state the minimum cross-section for its terminals, and this listing does not.
100 A charge · maximum PV voltage not published · tracking efficiency not less than 99 % · sealed, gel, flooded and LiFePO4 · LCD with single-touch settings and seven modes · wiring sizes not published · described as waterproof without a rating
A 100 A controller for 12 to 48 V systems with dual 5 V USB ports, single-touch settings and protection against over-voltage, over-current, over-charge and deep discharge.
Best for: An outdoor or semi-exposed installation where the protections list is the deciding factor.
60/80/100 A selectable · maximum PV voltage not published · MPPT algorithm named, efficiency not published · lead-acid and lithium · backlit LCD with live data and fault codes · wiring sizes not published · three-layer protection
A controller selectable at 60, 80 or 100 A for 12 to 48 V systems, with seven intelligent modes including dusk-to-dawn operation for street lighting.
Best for: A street lighting or garden installation where the timing modes do most of the work.
20 A charge · 100 V maximum PV input, in the model name · multi-stage adaptive algorithm · presets for common types plus fully custom profiles · Bluetooth with VictronConnect and GX compatibility · wiring sizes not published · enclosure not rated
A 20 A SmartSolar controller whose model number states its limits — 100 V input, 20 A output — with a multi-stage adaptive algorithm, battery presets and integrated Bluetooth.
Best for: A system that will grow, where the controller has to fit into a wider monitoring installation later.
